Muscles worked
Setup
- Stand tall with your feet shoulder-width apart and a slight bend in your knees.
- Extend your arms out to the sides at shoulder height, forming a 'T' shape with your body.
- Turn your palms forward and slightly retract your shoulder blades to open the chest.
- Maintain a soft bend in the elbows to protect the joints throughout the movement.
How to do it
- Exhale and slowly bring your hands together in a wide arc in front of your chest, as if hugging a large tree.
- Squeeze your chest muscles forcefully as your hands meet, holding the peak contraction for one second.
- Inhale and slowly reverse the movement, returning your arms to the starting 'T' position until you feel a light stretch in the chest.
- Maintain a controlled tempo of 2 seconds to close and 2 seconds to open.
Form checklist
- Keep your shoulders depressed (down) and away from your ears.
- Ensure your arms stay at shoulder height; do not let them drop toward your waist.
- Avoid arching your lower back or leaning forward as you move your arms.
- Keep your core engaged to stabilize your torso throughout the set.
Pro tips
- Focus on 'pushing' with your inner elbows rather than just moving your hands to better isolate the pectorals.
- Create internal resistance by tensing your chest and arm muscles as if you are moving through thick water.
Make it harder
- Slow the eccentric (opening) phase to 5 seconds to increase time under tension.
- Perform the movement while standing on one leg to add a significant core stability challenge.
