Side planks are a great exercise to work on for a full body workout. I like to do these in between exercise sets to keep my body moving and working.
Side plank target your upper body by engaging the shoulders and back along with your core including your obliques. They also hit your lower body by targeting your glutes, hamstrings and quads. As you can see side planks are a great exercise to preform and get good at.
Work on these back exercises to get your back into great shape...to keep a cardio element to this workout have your stations set up and go lighter on the weight and keep moving without much transition time between exercises.
