Glutes specifically. I think that you could get some decent activation using ems on the glutes as compared to the exercises on the tnation link. I improved my standing broad jump by 4-6 inches. My med ball feels stronger too. My form is a little off but i feel it’s stronger since I have been stimming more often.
Here’s a quick vid from yesterday. My form is off but PJ gave me a few pointers on how to fix it.
