Time Under Tension
The total duration a muscle is under strain during a set, influenced by rep speed.
Detailed Explanation
Time Under Tension (TUT) refers to how long a muscle is working during a set. Slower, more controlled reps increase TUT, which can enhance muscle hypertrophy by increasing metabolic stress and mechanical tension. A typical hypertrophy-focused set should last 40-70 seconds. For a 10-rep set, this means each rep takes about 4-7 seconds. Controlling the eccentric (lowering) phase for 3-4 seconds is particularly effective for muscle growth.

Fitnit's rep counter measures how long each rep takes, so slowing the eccentric to 3-4 seconds for time-under-tension training is something you can actually verify rep by rep.
