inclines are fine for me, they boost both my flat bench and my shoulder press
Incline bench presses don't help Flat Bench Presses. Flat Bench Presses help Flat Bench Presses. Incline bench presses don't help Military Presses. Military Presses help Military Presses. Incline bench presses place shoulder joints in a completely vulnerable position, and wreck them. I know that sounds basic, and I can get into advanced physiology, but it would serve little purpose. Most gym members need to make the transition from "gym member" to "body builder". 80% of new muscle is acquired through two exercises: the Full Squat and the Flat Bench Press, both with free weights. Not hanmer strength this and body solid that. You wouldn't train for a marathon by driving an automobile so don't train for muscles in a machine either.
