Mountain climbers are great total body exercise. You are going to be utilizing your core because you are starting from a plank position. Your shoulders have to stabilize your upper body. Your triceps have to work isometrically to keep you in place. And then you are gonna be moving your legs, so you are getting some work in the hip joint. And also because you are usually doing them pretty quickly, it becomes a very cardiovascular type movement. So getting into your plank position, hands a little wider than your shoulders.

Abdominals are braced. And then you are gonna draw one knee in without lifting the hips up. So you might kinda feel like your legs are skimming the floor. If you are not that flexible you take it to whatever range you can without the hips elevating. So your mountain climber might start here, it might come all the way in. That’s just a flexibility issue. And you are gonna alternate legs. The faster you go the more that heart rate is gonna come up. Again keeping the arms over or the shoulder over your wrist is were key to being able to maintain the plank. So you are looking not for your hips to be in the air, but for your hips to be low and your quad contracted.

And then just moving in and out; nice and quickly. Getting that action in the legs, getting the action in the arms. Just a great total body exercise..
