Time Under Tension

The total duration a muscle is under strain during a set, influenced by rep speed. 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.

Time Under Tension is a core training concept that directly impacts your workout results. Applying it correctly to your exercise routine leads to more efficient workouts and faster progress toward your strength and muscle goals.

Apply time under tension to your workouts by understanding the underlying principle and incorporating it into your training plan. Fitnit helps you track your progress and maintain proper form with AI-powered workout tracking.

Time Under Tension is closely connected to Hypertrophy, Rep, Set. Understanding these related concepts together gives you a more complete picture of training science and helps you make better decisions about your training program.
