You have probably all done or atleast seen the normal chest press, but there are some things you can do in addition to the regular chest press to increase the work you're doing. Grab a physioball and place it under your upper back. Keep your knees inline with your ankles and be sure to press those hips up. You want to squeeze your glutes the ENTIRE time. You'll start to feel it in your hamstrings, your glutes, and your lower back. Keep those abs tight as well. Do a set of 8-12 reps here.
If you want to add to the burn, when you are finished with your set of chest presses place your weights in the creases of your hips. Dip your buns down to the ground to where they are almost touching the floor and press your glutes back up to the ceiling as high as you can get them. Remember to sqeeze. Do 15 of these!
