Comparing the StrengthErg to Traditional Weight Training

Strength training is dominated by machines and free weights. But the Concept2® StrengthErg™ offers a unique, data-driven alternative. In this article, we will explore how the StrengthErg compares to traditional strength training methods. 

A Quick Recap: Traditional Strength Training 

Strength machines are often simple to use, offer guided motion, and target specific muscles. Free weights offer greater variation and engage stabilizing muscles. But weights can be intimidating and require proper technique knowledge to mitigate against the potential for injury.  

Enter the StrengthErg 

The StrengthErg is a flywheel-based resistance trainer. Unlike traditional strength training, you do not select the weight and then try to move it. Instead, you perform the movement, and the monitor tells you what you did. The force you apply determines the resistance you feel. More force, more resistance. Less force, less resistance.  

Concentric-Only Movement 

Most traditional lifting includes both eccentric (lengthening) and concentric (shortening) phases of the movement. Eccentric movements are important for muscle growth, but as a result they cause more muscle breakdown and require longer recovery. The StrengthErg only loads the concentric phase, which reduces post-workout soreness and shortens recovery time compared to eccentric movements. This makes it especially suitable for high-frequency and sport-specific training. 

Force at Every Point in the Range 

With weights, the amount of force you apply is dictated by your weakest position in the lift. On the StrengthErg, you can apply maximum effort at every point of the movement, maximizing muscle engagement throughout. 

Variable Resistance Without Pins or Plates 

By adjusting the damper setting, users can modify how the flywheel reacts. A higher damper makes the movement slower. A lower damper allows for faster, more explosive movements. 

This lets athletes target distinct parts of the force-velocity curve. The force-velocity curve describes the inverse relationship between the force a muscle can produce and the speed at which it contracts. As velocity increases, the muscle's ability to generate force decreases. This allows you to train at a variety of resistances. From high-force, low-speed lifts and fast, explosive training on the StrengthErg, all without changing equipment or weights. 

Safety: You Cannot Fail a Rep 

With the StrengthErg, there is no risk of failing a lift under a heavy load. It only resists the effort you put into it. You can go all-out on a rep, or stop applying force part-way through, without fear of dropping a bar or getting pinned. This ensured greater safety while exercising and can be particularly important for those unsure of their current strength level or people that lift without a spotter. 

Objective Data Tracking 

The StrengthErg paired with ErgData tracks and records your data. Review metrics of force, reps, time, work, drive speed, time under tension, and much more. The data is ideal for monitoring progress, creating challenges or competitions, and sport-specific training. For example, a rower can train their leg drive on the StrengthErg while measuring their drive length and drive speed. Using the damper to control the force-velocity relationship, they can precisely replicate the on-water range, speed, and load. 

How They Complement Each Other 

Rather than replacing traditional strength training, the StrengthErg offers a complementary training modality. Free weights remain valuable for working accessory muscles, improving joint stability, and balance. The StrengthErg offers safe, powerful concentric training, perfect for explosive work, testing, and high-frequency conditioning. 

Rehab and Evaluation Ready 

Because you do not need to select a load, and the flywheel adapts to your force, the StrengthErg is perfect for rehab environments. Clinicians can evaluate baseline strength, track changes over time, and scale difficulty without risk of injury. This also enables objective re-entry criteria for return-to-play decisions. 

Strength Training, Evolved 

Whether you are an elite athlete, just getting into strength training, or returning from injury, the StrengthErg delivers smart, safe, and scalable resistance training that evolves with your needs. 

By combining the benefits of traditional lifting methods with the innovation of flywheel resistance, the StrengthErg represents a new option in performance, recovery, and data-driven training.
