How to Perform TRX Alternating Knee Tucks

1. Set Up: You should already have the TRX straps attached to an anchor point above you. Adjust the straps so they hang down to about mid-calf length.

2. Starting Position: Place your feet in the TRX handles / foot cradles and get into a plank position with your hands directly under your shoulders, body forming a straight line from head to heels.

3. Perform the Tuck: Keeping your core engaged, draw one knee towards your chest while the other leg remains extended. Ensure your back stays flat and your hips do not sag or lift excessively.

4. Alternate Sides: Extend the bent leg back to the plank position while simultaneously drawing the opposite knee towards your chest.

5. Repeat: Continue alternating sides for the desired number of repetitions.

TRX Alternating Knee Tucks Common Mistakes to Avoid

Sagging Hips: Ensure your hips stay in line with your body and do not drop towards the floor.

Rounded Back: Keep your back flat and avoid rounding your shoulders to maintain proper form.

Rushed Reps: Perform each rep with control to maximise muscle engagement and reduce the risk of injury.

Inconsistent Breathing: Maintain a steady breathing pattern, exhaling as you tuck your knees in and inhaling as you return to plank.

Reps and Sets

It’s on you to determine how many reps and sets you should perform. It depends on your goals, but more generally speaking, it depends on how many reps you can actually do.

Beginners: Start with simply mastering the move. Keep in mind that if you’re just starting out, 4 reps is a valid set.

To determine how many reps/sets of TRX Alternating Knee Tucks you should start with, you first need to figure out how many reps you can comfortably perform. Then add 2, and perform that number of reps for 3 sets.

For example; let’s say you can perform 4 reps comfortably. Add 2 to make 6 reps. Perform those 6 reps 3 times over, allowing yourself sufficient rest inbetween.

Experienced lifters: You know your body and its abilities better than anyone, use your own judgement.

We recommend that you avoid performing more than 12 reps per set. If you’re comfortably performing 12 reps for up to 6 sets, it’s time to make the exercise more challenging.

How to Make TRX Alternating Knee Tucks More Challenging

You can make this exercise more challenging by slowing the exercise down to increase your time under tension. You can also slow down half the exercise, so tuck in at normal speed and then slowly release your feet back to start position in a clean and controlled movement.

Another option for making TRX Alternating Knee Tucks more challenging is to wear a weighted vest or belt for added resistance. When you get really good you can ask someone to balance a weight plate on your back.
