Side plank + arm work = a whole lot of connection! 🔥
Holding the side plank challenges your obliques, core and shoulder stability, while the spring adds resistance for straight and horizontal adduction of the arm.
The challenge is keeping the body strong and steady while the arm moves independently.
Core stability + shoulder control + upper-body strength. 💪
Looks simple… definitely doesn’t feel simple. 😉
