Depending on the client and thier physical ability I use the stability ball to either progress or regress exercises. My top 5 exercises include (no specific order):
1. Stability Ball Pike
2 Stability Ball Knee In
3. Stability Ball Push Up (Toes on as progression, shin’s on as regression, or hands on for shoulder/core stability)
4. Alternating or 1-Arm Chest Press (Engages core stability)
5. Rainbow Twist (Similar to Russian Twist but instead of ball/arms crossing chest level, carry ball from one side, and then above head as your forming a rainbow)
You can also regress form TRX and use stability ball to perform Atomic Push or Push w/Pike.
