Though he was a bit chunkier in his early days, the mainstream's introduction to 50 Cent came with him doing chin-ups and running on a treadmill in the "In Da Club" video. While ten years have passed since then, and plenty of money has flowed his way, Fif has remained in shape throughout, enough to cover Muscle & Fitness magazine this very month.

Apparently, inside the issue, the rapper shares his workout routine, so if you're trying to be ripped at 39, you might wanna check it out. The issue is set to hit stores on Fif's 40th, which is July 6th.
