Plank jacks vs mountain climbers

Although it’s tough, when done correctly, the Forearm Plank strengthens the abs, legs and core . It is also good for stretching the arches of your feet as well as your calves, shoulders and hamstrings.

That’s the concept behind mountain climbers. Performed from a plank position, you’ll alternate bringing one knee to your chest, then back out again, speeding up each time until you’re “running” against the floor .

As a compound exercise that utilises multiple muscle groups in your whole body, mountain climbers are an effective way of strengthening your arms , back, shoulders, core and legs. Another benefit of using multiple muscles at once is an increased heart rate, which will help you burn more calories.
