Peloton’s 聽featured insight from聽Alexander Rothstein, M.S., coordinator and instructor for the exercise science program, in an article about time under tension. Rothstein explains that muscles undergo multiple types of contractions: concentric, isometric, and eccentric. A muscle is under tension during all three of these contractions.
鈥淭ime under tension represents the total amount of time spent in all of these phases for a given set or workout session,鈥� Rothstein explains. As such, several factors determine the amount of time under tension in a workout: the total amount of time you鈥檙e exercising; the number of reps and sets you鈥檙e doing (i.e., the training volume); and the amount of time each rep takes.
