Develop a stronger core and build explosive upper body power with three standing ab exercises and minimal equipment. The routine only takes 15 minutes to complete and can be scaled to your ability as you get fitter and stronger — so here’s how to do it.
For the workout, I recommend one of the best kettlebells for weight training and a medicine ball; this just needs to be a heavy ball (or similar) you can safely slam on the ground without making enemies out of your neighbors or hitting yourself in the face on the rebound.
