Step Jacks with Push Back
Step feet side to side in a low-impact jack while pushing both arms straight back at shoulder level to engage the posterior deltoids and rhomboids.
Key points
- Keep arms held high at shoulder level throughout the entire 45 seconds
- Squeeze the upper back muscles on every backward push
Common mistakes
Allowing arms to drop below shoulder height due to fatigue.
