What exercise can replace mountain climbers?

Plain and simple, a weak core will make it extremely difficult for you to perform mountain climbers correctly, says Tripp. Essentially, the mountain climber is just an active plank. So, if your hips and midsection are sagging, and your knees are banging against the floor, nailing the move will be nearly impossible.

The dos: – Realistically, if you’re a beginner, Briant said to start by doing 10-15 mountain climbers in a row . If you’re a little more advanced, sets of 25-30 is a good goal. – Bring your knees as close into your chest, with a slight pause, for maximum ab work.
