I like doing the push-up with my feet on the big core balls ,feet are raised about 2 to 3 feet depends on the ball size .Mix it in on chest day ..man what a pump in the chest area ..if you really mash a lot of them out at the end ..do as many as you can do ,stop catch your breath and mash out some more and keep going until you can't possibly do anymore ... You will be so sore in the chest next day but kicks those pecs in gear.
