Try incline benching like this to build muscle, build strength, protect your joints, and put a little more explosiveness in your chest training.
Load up the bar for incline bench pressing. Then add chains that aren't completely off the ground at the start. This will lighten the load as you lower the bar. It also means that as your arms reach the top the load will get heavier.
How many reps can you do for two alternating exercises in 15 minutes? This is just a taste of how escalating density training works. It’s a brutal, but fun way to build muscle and improve conditioning.
