How to do overhead medicine ball slams: Standing tall with your feet hip-width apart, hold a medicine ball with both hands. Reach both arms overhead, fully extending your body. Slam the ball forward and down toward the ground. Extend your arms toward the ground as you slam and don’t be afraid to bend your knees as you hinge over. Squat to pick the ball up and then stand back up.
I'm not telling you that it's easy, but it really is pretty simple. In an age where people don't even have to go outside to grill a steak, it's tempting to spend a few dollars on a quick fix. Human anatomy hasn't changed much throughout history, however. If you adopt your grandparents' work ethic and apply it to your every day life, you will achieve your greatest results.
There's no way around the fact that, when it comes to burning more fat, you have to work at it. There is no magic exercise, workout, or pill that will do the job for you. The good news is that it doesn't take much activity to push the body into that fat burning mode. Try incorporating some type of activity every day, even if it's just a quick walk, and build on that over time as it becomes more of a routine. Do that and you're on the way to burning more fat.
