What kind of hiphop is good for gym?
M.O.P. lol - depends on what you are doing. Some shit is for lifting weights. Stuff like Drake "jump man" is good for running.
Personally, anything by T.I. always pumps me up to ensure I have a solid workout.
Anything with hardnock and 808. Metroboomin provides. Or bump this soundcloud.com/BennPeterson
