I wanted to get like, a weighted jacket, so I could take it off and throw it on the ground and have it make a thud, like I'm piccolo, or rock lee, right, and maybe get jacked at the same time, but apparently it costs like 200 bucks for one. So that sucks.

Edit: Also, none of them taper at the waist, which I feel like would be a good idea since that would more evenly distribute the weight on your hips instead of just on your shoulders.
