THE AVERAGE GYM-GOING guy looking to build some muscle and size probably does 3-4 sets of anywhere from 6-10 reps. That’s a pretty large range for a workout, even before you consider factors like how fast or how intensely you’re lifting. By focusing on timed sets rather than hitting a specific number of reps, you can directly influence the intensity of the set and spur huge gains in size and strength.
What is ‘time under tension’ training?
Time under tension (or TUT for short) is commonly used in strength and conditioning and bodybuilding. Essentially, it refers to how long a muscle is under strain during a set. A typical set of 10 reps for an average lifter will take anywhere from 15-25 seconds depending on lifting speed. By putting a muscle under longer bouts of strain, you can cause extensive muscle breakdown leading to sleeve-busting muscles.
