Time Under Tension
Definition: The total duration a muscle is under strain during a set. Slowing down the eccentric (lowering) phase to 3-4 seconds can increase muscle activation and hypertrophy stimulus.
Detailed Explanation
Time Under Tension (TUT) refers to the total duration a muscle is held under load during a set. Controlling the tempo increases mechanical tension.
Practical Application & Guide
Focus on the eccentric (lowering) phase of your lifts. Control the weight down for 2-3 seconds to maximize the hypertrophic stimulus.
Common Pitfalls & Mistakes
Slowing down the concentric (lifting) phase excessively, which decreases power output and overall force production.
