You knew that Chad Vaughn (@olychad) is a fan of Close Grip Overhead Squats.
Here he does tempo work with them.
LOTS of core, mobility, and strength work all in one! 305lbs for 5sec down and 10sec hold. The goal in the next few months is 160kg(352lbs)!
If you are blessed with mobility give this one a try.
Also see his Clean Grip vs. Snatch Grip Overhead Squat video.
That’s a thing of beauty.
