The Concept2 StrengthErg is a multifunctional strength training machine. It uses the power of air resistance to deliver a comprehensive and safe workout without the need to deal with weight plates, racks and barbells. You can apply as much or as little force as you want and the StrengthErg will accurately measure and display your result.
The StrengthErg is powered by Concept2’s signature flywheel technology, which can be varied in intensity depending on the combination of the damper setting and the amount of effort the user produces. The responsive nature of air resistance results in a variable load depending on the user’s strength. A lower damper setting, or less air resistance, produces a lighter feel when pressing or pulling. A higher damper setting, or more air resistance, produces a heavier feel when pressing or pulling.
Another advantage of responsive resistance is that as your strength varies from one point in a lift to another, the resistance reacts to match. In traditional lifting, you can only put on the bar as much weight as you can lift at the weakest point in the lift, which may not be enough to challenge your muscles in the stronger part of the lift.
You can move easily between three basic positions: leg press, chest press, seated row with a wide range of variations and custom movements possible from each position. You can choose whether to work out at a low number of reps for a high amount of force, or you can choose to do a high number of reps and work on your muscular endurance. It’s quick and easy to adjust the damper setting to make the movement slower or faster, so you can get the exact relationship between speed and force that you want for your training.
