Bouncing Push Ups 

Developing a big strong chest, requires activating fast twitch muscle fibers. Strength and speed are closely related. Combining these two qualities is what gives you power. 

You can make this movement harder by elevating your feet. You can make it easier by elevating your hands. 

Try this- do a few bouncing push ups, and then immediately transition to regular push ups, and lastly, switch to negative push ups. 

Another great option is to do 10 sets of 2-4 reps with short 15-30s breaks.
