5 year old Claudio Stroe demonstrates the proper technique for doing pushups while balancing only on glass bottles. 5 year old Claudio incorporates many different skills into his strength training and you can see the results at the end of the video. Claudio is a professional so please don’t try this at home if you’re thinking you’re stronger than a 5 year old. The good news is that this works best with large empty bottles so emptying those is something just about everyone much older than Claudio can accomplish.
