Freezing During an Interval Workout After a Certain Number of Intervals


When doing an interval workout the monitor appears to freeze after a certain number of intervals.


You are using ReRow/ReSki. This repeats a prior workout with the PaceBoat/PaceSkier set to the speed of the earlier workout. ReRow/ReSki workouts will only have the same number of intervals as the original. If you want to do a larger number of intervals, you will need to create a new interval workout.

Setting Up a Biathlon

BiathlonBiathlon combines two sports: typically Nordic skiing and target shooting. Races generally consist of three or five laps, with a shooting stage (“range”) between each lap. A penalty is assessed for each missed shot. Most often, this is a penalty lap of 150 extra meters of skiing.

You can use the Biathlon Workout to ski or row intervals alternating with target shooting or some other activity. You can choose from several penalty distances, or no penalty at all:

  • With penalty: Penalty distances are calculated after each range interval and must be completed before the next interval begins.
  • Without penalty: No penalty distances are calculated. You will simply have an undefined rest time of up to 10 minutes between your intervals.

The computer keeps track of your range time and your total elapsed time. Penalty laps show up on the logged workout detail as a separate interval with zero rest. You can Re-Ski or Re-Row the workout, but penalty intervals and range time will be exactly as they were when you completed the workout originally.

To set up a Biathlon, from the Main Menu choose Select Workout > New Workout > Special > Biathlon.

During set up, choose the number of intervals you want (from 2 to 15), the interval length, and whether you want a penalty (choose from none to 250m in 50m increments). Do your first interval. When you complete it, the rest or range time begins, and the PM will prompt you to stop skiing or rowing. Once you’ve stopped, the penalty screen will appear on the PM:

  • Playing with penalty: After completing your range time, press the button that corresponds to the number of penalties you incurred (from 0 to 5). For example, if you were shooting, choose the number of shots missed. The PM calculates the penalty distance based on what you selected during set up (selected penalty increment multiplied by the number of penalties/shots missed equals the penalty lap distance). Do the penalty lap. When you are done, your next interval begins.
  • Playing without penalty: Simply press Continue when you are ready to begin your next interval.


  • Only PM3s running PM3 Firmware Version 303 or higher include Biathlon.
  • On PM3s and PM4s, the menu path for setting up a Biathlon starts at the Main Menu and is Games > More Games > Biathlon.

Fish Game

The Fish GameThe Fish Game teaches you how to modulate intensity. The object of this game is to rack up as many points as possible by eating the nutritious fish while avoiding the large, toothy beasts that will send your score plummeting to the ocean floor.

On the PM screen, you're the fish facing the onslaught of fellow ocean-dwellers, both good and not-so-good. Alter your intensity to move your fish up and down the left-hand side of the screen. When an edible “good” fish comes your way, try and gobble it up to get points (small fish are worth 30 points; striped fish are worth 60 points). Avoid the large predators, as they’ll take 45 points off your score if they catch you.

Each game lasts four minutes, with a play again option at the end. Your Fish Game workout information (time, distance, pace per 500 meters, and so on) is saved to your LogCard or PM Memory, just like a regular workout.

To set up a Fish Game:

  1. (PM5 Only) From the Main Menu select More Options > Games > Fish Game.
  2. (PM4 Only) From the Main Menu, select Games > Fish Game.

Checking Your Firmware Version

  1. Power up the PM3 and access the Main Menu. (If you use a LogCard to turn on the PM3, or if there is a LogCard in the PM3 when you turn it on, you will need to select a user on the LogCard, and then select Main Menu.)
  2. From the Main Menu, select More Options > Utilities > Product ID. The PM3 displays the Product ID screen, which lists the firmware version the monitor is running. The Product ID screen has evolved over the years and will look like one of the following examples depending on which firmware version you have.

Understanding Stroke Rate

Stroke rate is the number of strokes you take per minute, or spm (Strokes Per Minute). The PM displays this number in the upper right corner on every workout display.

For rowing, a stroke rate between 24 and 30 strokes per minute is typical for most workouts. When racing, stroke rates are generally a bit higher but usually still below 36.

For skiing, the stroke rate will generally be between 30 and 40.

An important notion to understand is that an increased stroke rate does not necessarily mean that you are working out with more intensity. Instead, the key to increasing intensity is knowing how and when to apply power. Focus on getting as much power as you can into each drive/pull. To focus on this power:

  • For rowing, think of using a ratio of one beat on each drive for every two beats on the recovery. In other words, don’t rush as you travel up the slide to take the next stroke. Instead, relax on the recovery as you prepare for the work of the next drive. See How to Row Harder for more information.
  • For skiing, the drive and recovery are generally much closer in length.

As you do this, watch the PM for immediate feedback on your intensity. As your intensity increases, your pace per 500 meters will decrease, and your watts and calories will increase. For more information on monitoring intensity, see Understanding and Changing Units.

Understanding and Changing Units

The PM provides three different units for showing your workout intensity:

  • Pace per 500 meters—How long it takes you to row or ski 500 meters: the smaller the value, the faster your pace. The monitor displays your pace per 500 meters for each stroke as well as your average pace per 500 meters for the workout.
  • Watts—Your power output, in watts: the higher the value, the more power created. The monitor displays watts for each stroke as well as your average watts for the workout. For information about the formula used to determine watts or to calculate pace-to-watts or watts-to-pace, visit the Watts Calculator page.
  • Calories—The number of Calories burned: the higher the value, the more Calories burned. During a workout, the monitor displays the total Calories burned and also translates this to a Calorie/hour value (when viewing results, the monitor displays the Calorie/hour value). To calculate Calories, the monitor uses a formula based on a 175 pound individual. To calculate Calories burned for your body weight, visit the Calorie Calculator page.

At any time during a workout or while viewing workout results, press Units or Change Units to view your workout intensity in a different unit; the PM cycles through the different units with each successive push of the button. In addition to pace, watts, and Calories, scrolling through units also displays total time or meters elapsed for the workout or interval, depending on the workout type.

Understanding Workout Types

The PM allows you to program several types of workouts…or none at all if that’s your preference. Read on to learn the basics.

Just Row/Ski

If you’re not the button-pushing type, just hop on an indoor rower or SkiErg and start pulling; the monitor will power up and begin displaying your workout data after a few seconds. This type of workout has no set duration and is known as Just Row or Just Ski. When doing a Just Row/Ski, the monitor counts up from zero.

Just Row/Just Ski workouts can be up to 50,000 meters, and you must row or ski for at least one minute for Just Row/Just Ski results to be saved in memory or on your LogCard. For more information, visit Just Row/Ski.

Single Distance

A Single Distance workout is when you program the monitor for a certain distance (500 meters, 5000 meters, 10000 meters, etc.) with the intention of completing the distance programmed. When doing a single distance piece, the monitor counts down from the number of meters programmed and displays the time to the tenth of a second at the finish.

Single Time

A Single Time workout is when you program the monitor for a certain time (30 minutes, an hour, etc.) with the intention of working out for the amount of time entered. When doing a single time piece, the monitor counts down from the amount of time programmed and displays your total meters at the finish.

Single Calorie

Note: This option is available on PM5s only.

A Single Calorie workout is when you program the monitor for a certain number of calories (20, 50, 70, etc.) with the intention of working out until you have burned the number of calories entered. When doing a single calorie piece, the monitor counts down from the number of calories programmed and displays your time to the tenth of the second at the finish. To view how many meters you completed during that time, view the result in memory.

To understand how the Performance Monitor calculates calories, visit the Calorie Calculator page.


Interval workouts are workouts that have periods (intervals) of work followed by rest time during which you might stop completely or, more typically, keep the flywheel spinning at a very easy pace. Interval workouts can be time based, distance based, calories based or variable:

  • Time based—During each interval, you work for a predetermined amount of time and then rest for an amount of time before beginning the next work interval (see Setting Up a Time Interval Workout)
  • Distance based—During each interval, you work for a predetermined distance and then rest for an amount of time before beginning the next work interval (see Setting Up a Distance Interval Workout)
  • Calorie based—During each interval, you work until you burn a predetermined number of calories and then rest for an amount of time before beginning the next work interval.
  • Variable—The workout contains a mix of time and/or distance intervals each followed by rest time (see Setting Up a Variable Interval Workout)

Rest Time—Predetermined or Undefined

When setting rest time for an interval workout, you can either specify a set amount of time or set the rest time to undefined, which allows the rest interval to be undetermined. Undefined rest is helpful for workouts such as CrossFit workouts that combine indoor rowing/skiing with other activities off the indoor rower or SkiErg (box jumps, kettle bell swings, etc). See Setting Up a Workout with Undefined Rest for more information.

Preset Workouts

Preset Workouts are pre-programmed workouts—workouts that are already set up in the Performance Monitor. The PM includes five standard workouts and five custom workouts. For more information, see:


Special Workouts include Biathlon and Ergathlon. Biathlon alternates erg work with another test. Traditionally the sport of Biathlon includes target shooting, but any other challenge of accuracy can be used. Ergathlon is an event using all three Concept2 ergs. The PM5 offers a selection of Ergathlon distances to choose from.

Resolution for Error Codes 120- through 129-

Error codes 120- through 129- occur when the monitor is being used with external or third-party software. If you receive this error, you should update the monitor firmware. With the exception of Concept2 ErgData, this error could also indicate a problem with the third-party software and not the monitor. If updating the monitor firmware does not resolve the issue, please report the problem to the software vendor.

For instructions on how to update your monitor firmware, please visit the appropriate page: PM3 | PM4

Problems Using the iConnectConcept2 Cable

The iConnectConcept2 cable is used to connect a PM3, PM4 or PM5 (wired PM5 connections only) to an iOS device for running applications such as ErgData. If you are having trouble connecting the iConnectConcept2 cable to your iOS device, the information on this page may help.

When ErgData prompts you to connect the Concept2 Cable, plug the iConnectConcept2 cable into your iOS device with the bulge facing the front of the iOS device (see image below). The message on ErgData should change to "Please connect the PM." If it does, follow the next prompt displayed. If it doesn’t, or if you are prompted for an update, read on.

When Prompted for an Update—What It Means

To facilitate communication between Concept2 monitors and iOS devices, the iConnectConcept2 cable itself runs firmware. This is separate from the firmware running the Concept2 monitors. The cable firmware is the brain that allows communication between the two devices (the PM and the iOS device) to occur.

When you first plug the iConnectConcept2 cable into the iOS device, it will check for current firmware and prompt you if an update is needed. If you get this prompt:

  1. Make sure the cable is NOT plugged into the Performance Monitor, and then accept the update. Even if you receive an error during the update, let the update finish, and move on to the next step.
  2. Once the update is finished, you will be instructed to remove the cable from the iOS device and re-insert it. If the update was successful, you will be prompted to connect a PM. If the update was unsuccessful, you will be prompted again to update the cable firmware. Attempt the update again. If it continues to be unsuccessful after several attempts, contact Concept2 for assistance.

When “Please Connect the PM” Doesn’t Appear

If you weren’t prompted for a cable firmware update, or if you were and you completed it, and “Please Connect the PM” still does not appear, take the following steps:

  1. Make sure that the cable is fully plugged in with the bulge facing the front of the iOS device (see image), and that it is plugged directly into the iOS device (remove any adapters, extension cables, etc.).
  2. Inspect the connector for damage.
  3. If you have an iOS device with a Lightning connector and are using a Lighting-to-30-pin adapter, ensure it is genuine Apple. Adapters not manufactured by Apple do not work. See iOS Requirements for more info.
  4. Check whether other accessories work when plugged into the iOS device.
  5. Turn the iOS device completely off, wait a few minutes, then turn it back on and try again.
  6. If the problem persists, contact Concept2.

When “Please Connect the PM” Appears but ErgData Doesn’t See the Connection

When a PM is successfully connected, ErgData will display “PM Connected.” Otherwise, it will continue to display “Please Connect the PM.” If you have plugged the iConnectConcept2 cable into both devices, but ErgData doesn’t recognize the connection, take the following steps:

  1. Make sure the USB plug is oriented correctly (see image) and is not plugged into one of the networking RJ45 jacks.
  2. Inspect the cable for damage.
  3. Try connecting the PM via USB to a Windows computer to ensure that the USB port on the PM is working. If the PM cannot connect to a Windows PC, disconnect the USB, remove the PM batteries overnight, then try again.
  4. Make sure your PM firmware is up to date.
  5. If the problem persists, contact Concept2.
