The Swiss Ball Dumbbell Alternating Chest Press is a pressing exercise where you rest your upper back on a Swiss ball and press dumbbells up one arm at a time. It mainly trains your chest, front deltoids and triceps. Your glutes and trunk work to hold your hips up and stop you rolling.

How to do the Swiss Ball Dumbbell Alternating Chest Press

Coaching cues

Common mistakes
- Letting the hips sag. Squeeze your glutes and keep a straight line from your shoulders to your knees.
- Rolling to one side as you press. Brace your core and set your feet a little wider. Slow the press down.
- Flaring the elbows straight out. Keep your elbows at an angle to your body as the dumbbell comes down.
- Rushing between arms. Finish one full rep with control before you start the other arm.

Training focus and energy demand
This press is used to build chest, shoulder and triceps strength while also training your trunk and hips to hold steady. It suits lighter weights, because balance limits how much you can press.
Several energy systems work together, and their share changes with load, speed, set length and rest. Short, hard sets lean more on fast energy stored in the muscle. Longer sets with short rests lean more on aerobic energy. Hard efforts that last from several seconds to a few minutes also rely heavily on energy your muscles make quickly from carbohydrate.
FAQs
Why press one arm at a time?
Pressing with one arm loads one side more than the other. Your trunk has to work to stop you rotating, which adds a stability challenge.
How do I get off the ball safely?
Bring both dumbbells to your chest, lower your hips and walk your feet back toward the ball until you are sitting up.
