Setup
- Stand in a staggered boxing stance with your non-dominant foot forward and knees slightly bent.
- Hold a light dumbbell in each hand at chin height with a neutral grip (palms facing each other).
- Tuck your elbows close to your ribs and engage your core to create a stable foundation.
How to do it
- Exhale as you punch one dumbbell straight forward, rotating your wrist so the palm faces the floor at full extension.
- Pivot slightly on the ball of your lead foot and rotate your torso to drive the punch from your core.
- Inhale as you quickly pull the dumbbell back to the starting position at your chin with a controlled 'snap'.
- Alternate arms for the desired number of repetitions, maintaining a rhythmic tempo.
Form checklist
- Keep your non-punching hand up by your chin to protect your face.
- Avoid fully locking out your elbow to prevent joint strain.
- Keep your shoulders retracted and down, avoiding the urge to shrug toward your ears.
- Ensure your power comes from torso rotation rather than just the arm.
Pro tips
- Focus on the 'retraction' phase; pulling the weight back quickly is just as effective for shoulder stability as the punch itself.
- Imagine punching through a target rather than just at it to ensure full extension and muscle engagement.
Make it harder
- Increase the tempo to a 'speed' round to prioritize cardiovascular conditioning and fast-twitch fiber recruitment.
- Incorporate a 'slip' or a small squat between punches to turn the movement into a full-body metabolic exercise.
