While there is probably no need get into the “how” of jumping jacks, as we assume everyone is at least familiar with the mechanics, unfortunately familiarity breeds contempt and this workout is often overlooked due to its percieved simplicity. It can be an amazing warm up though, and if you are having trouble finding space to run/jog, a thousand jumping jacks make for an excellent cardio workout.
Muscles worked: lats, traps, biceps, rhomboids, deltoids
Depending on your grip (overhand, underhand, spread) you are essentially working out your entire back. Like table rows, however, this exercise requires something for you to grab.
Muscles worked: calves
Not surprisingly this exercise targets one muscle – your calves. You don’t need much space to do it but if you can find a slight ledge, as in the image above, it will allow you to have a greater range of motion.
Muscles worked: deltoids
Although at first glance this exercise may seem trivial, beggars can’t be choosers. If you want to work out your shoulders without a gym you need to improvise. Besides, after the thousands shoulder circles we guarantee you that you’ll feel it. If you don’t though, put something in your hands.
Muscles worked: quads, calves, hamstrings
This is a dynamic exercise that only requires an elevated surface. Once you figure that part out you’re ready to break a serious sweat. Just jump up onto the box/park bench/bed/etc. and then jump down again. Repeat this until your lower body is destroyed.
