Medicine Ball Slams
Medicine ball slams don’t look all that hard, but they’ll fire up your core in ways you might not expect. Take your time and really focus on using the muscles spanning from your glutes to your shoulders to power each slam and extension.
Stand tall with a medicine ball between your hands with your feet shoulder-width apart, knees slightly bent. Extend your arms over your head as you take a breath in, then using your core, slam the ball down to the ground just in front of your feet as hard as you can. Make sure you exhale as you perform the slam. Immediately pick the ball up and repeat the exercise.
