Lower and lift, that’s the typical way in which we perform gym based exercises whether they be bodyweight calisthenics, free weight dumbbell and barbell lifts or machines designed to hit specific muscle groups or movements.
We use these exercises to damage the muscle tissue within our workouts and through rest and quality nutrition and supplementation we can cause growth of muscle tissue to improve muscular size and strength for increased aesthetics and performance. The greater stimulation and damage we can cause to these tissues then the greater the potential growth and improvement and a key factor is at play for this within our workouts.
TUT- Time Under Tension
Quite simply this is how much time we load muscles within our workouts, with each exercise, set of work and even every repetition that we perform to stimulate growth in size and strength. Taking the same exercise, with the same repetition range, for the same total number of sets we can increase the effectiveness of the repetitions of that movement to get the results that we want.
For example, we perform the bench press for 1 set of 10. But this is carried out two different ways.
The first way is by performing the movement smoothly taking a second to lower the bar to the chest before squeezing the chest and triceps to push the bar back towards the celling to perform that repetition and this is then continued for each rep until we hit 10 and re-rack the bar.
The second way is by performing that same movement, however this time by lowering the bar for a count of 3 towards the chest before then squeezing our muscles to return the bar to top position for our set of 10 reps.
What’s the difference?
The difference between these two ways of performing the same exercise for the same exercise the same amount of times is that by simply altering the speed in which we perform our movement by lowering slowly we can triple the time under tension for those same muscle groups.
Our first way allowed us to perform 10 repetitions of the bench press with the muscles being under tension for around 20 seconds of total time for that 1 set. Our second way of performing those same 10 repetitions allowed us to load our muscles for around 40 seconds by lowering the bar slowly towards the chest.
This extra 20 seconds allow us to load muscles for longer periods which in turn causes greater stimulation and stress to those muscle groups which in turn will allow us to develop greater damage to the muscles and trigger a greater growth response for improvements in muscle thickness and strength. This is done by forcing the muscles to contract whilst lengthening against the weight which in turn causes greater damage to the muscle fibres.
Using it within my Workouts
There are many ways in which you can increase the time under tension with each repetition within your workouts. These include:
-
Lowering the weight for longer times– This is the same way that we increased the TUT within our bench press example. Simply increase the length of time you perform the first portion of the exercise such as lowering for 2-4 seconds and can be performed in many common exercises instead of our typical 1 second.
-
Pauses in the stretched position– This method requires you to control and hold the weight being lifted within the exercise in the full stretched position for 1-3 seconds before returning to the start position. This method allows us to increase the length of time that we perform the movement but also serves to improve our ability to control the weight that we are lifting. An additional benefit to using pauses within your workouts allow us perform movements with a full range of motion as we perform the pause at the best stretch possible before returning to the start.
Workout Example: Upper Body
A1- Flat Pause Barbell Bench Press 5 sets of 5 repetitions- Pausing for 3 seconds at the bottom
A2- Chest Down Row 5 sets of 6-8 repetitions- Pausing for 2 seconds at top position
B1- Incline Dumbbell Press- 4 sets of 8 repetitions- Lowering for 2-3 seconds
B2- Wide Grip Pull Down 4 sets of 10 repetitions- Lengthening for 2 seconds and pausing for 2 seconds with bar at chest
C1-Dumbbell Hammer Curl 3 x 10-12- 2 second pause at top position
C2-Overhead Tricep Cable Extension 3 x 10-12- 2 second pause at stretched position
