The JM press is an amazing tricep exercise invented by JM Blakely. It's one of the few movements that completely stretches out the triceps, which leads to bigger and stronger muscles.
Typically this exercise is performed with a barbell, but doing it with a safety squat bar reduces the room for error.
Most people mess up this exercise because they don't know how far down to go before moving the barbell toward the face. With SS-bar it's extremely easy. With the handles taken off, you bring the padding down to the chest, ease the bar to your nose, then reverse the movement.
You're punks. All of ya'. All of ya' under 25 or so, that is. Mike Mahler calls you "Generation Ent," for Entertainment, meaning you need to be constantly entertained. Well stand by to be entertained, in a manner of speaking.
Whether you're taking a planned break from training or you're struck by sickness or injury, there are plenty of things you can do to prevent muscle loss.
