Shortening of the muscle to generate force. This happens in the positive motion of a movement, like the upward portion of a bench press rep. Slide the timer to adjust how long you perform the concentric movement of each exercise.

- Concentric
Shortening of the muscle to generate force. This happens in the positive motion of a movement, like the upward portion of a bench press rep. Slide the timer to adjust how long you perform the concentric movement of each exercise.
- Isometric
The hold at the top or bottom of the movement. During this movement, the muscle is not changing in length, but still generating force. TrainCentric allows you to set how long you squeeze.
- Eccentric
The lengthening of the muscle. This contraction is the negative motion when performing a movement, like the downward portion of a bench press rep. Change the eccentric timer to increase time under tension.
- Reps
The number of repetitions of the motion you are performing. Typically those who are training for muscle size (hypertrophy) will use the 8-12 rep range, while those training for strength will work in the 4-6 rep range.
- Sets
The number of times you repeat the specified number of reps. Incorporating sets to failure will completely exhaust the muscle and break down muscle fibers. Build a workout in TrainCentric with a custom number of reps and sets for each movement.
- Rest
The rest in between each set. Set your rest period length and TrainCentric counts you down when it’s time to work again.
