Ring pushups are a challenging variation of the traditional pushup that engage more stabilizing muscles due to the instability of the rings. To perform this exercise, start by adjusting the rings to a height that allows you to maintain a plank position with your hands on the rings. Keep your body straight from head to heels, engage your core, and lower your chest towards the rings by bending your elbows. Ensure that your elbows are at a 45-degree angle to your body. Push back up to the starting position by extending your arms, keeping the rings stable throughout the movement. This exercise targets the chest, shoulders, and triceps while also engaging the core for stabilization.
