Sky Punch

Sky Punch Exercise Description

Sky Punch is a bodyweight, supine “reach” drill that trains controlled scapular protraction and retraction with the elbow kept straight. The primary focus is the serratus anterior, with the anterior deltoid helping maintain the arm position and the rotator cuff and scapular stabilizers providing joint control. Because the motion occurs at the shoulder blade on the rib cage, the movement is small and precise—your arm stays vertical while the shoulder blade glides forward and back. This pattern helps you practice keeping a neutral spine and quiet neck while the shoulder girdle moves smoothly. Expect a subtle burn around the side of the rib cage near the armpit as the serratus engages; you should not feel strain in the neck or lower back.

How To Do The Sky Punch Exercise

‘- Lie on your back with knees bent, feet flat, spine neutral, and head supported.
– Raise one or both arms so fists (or palms) are stacked directly over the shoulders; elbows straight without locking; wrists neutral.
– Keep shoulders relaxed (not shrugged) and ribs down.
– Without bending the elbows, reach your knuckles toward the ceiling by sliding the shoulder blades forward around the rib cage (scapular protraction).
– Pause briefly, keeping the arm vertical and neck relaxed.
– Draw the shoulder blades back to neutral on the rib cage without pinching or arching the back.
– Move smoothly in a small range; avoid rib flare, elbow bend, or chin jut.

Sky Punch Tips

‘- Keep your arm stacked so your fist stays directly over your shoulder the whole time.
– Straighten your elbows without locking them and keep your wrists neutral.
– Relax your shoulders away from your ears instead of shrugging.
– Keep your ribs down and spine neutral; avoid letting your ribs flare up as you reach.
– Reach your knuckles straight toward the ceiling by sliding the shoulder blade forward around your rib cage.
– Pause briefly at the top of the reach while keeping your neck relaxed and your arm vertical.
– Return the shoulder blade back to neutral without pinching it back hard or arching your lower back.
– Use a small, smooth range of motion rather than big, jerky movements.
– Avoid bending your elbows, flaring your ribs, or jutting your chin as you move.
– Notice a subtle burn along the side of your rib cage near your armpit, not strain in your neck or lower back.

Sky Punch Beginner Introduction

Sky Punch is a bodyweight drill performed while lying on the back that highlights slow, controlled motion of the shoulder blade rather than big arm swings. The arm stays pointed upward with the elbow straight, while the shoulder blade gently glides along the rib cage. This creates a targeted challenge for the muscles that wrap around the side of the chest, with the front of the shoulder and the deeper shoulder support muscles working together to steady the arm.

Because the action happens mostly at the shoulder blade, the movement feels subtle and precise instead of dramatic. The spine rests in a natural position and the neck remains calm while the shoulder area does the work. Many people notice a mild, focused fatigue along the side of the ribs near the armpit as those rib cage muscles wake up, rather than strain in the neck or lower back. This makes the drill a useful way to explore shoulder control, body awareness, and upper-body stability in a simple, low-load position.
