Equipment
How to do it
- Place an incline bench at 30 to 45 degrees centered under the Smith bar.
- Lie down so the bar lines up with the upper part of your chest.
- Grip the bar with a pronated grip wider than your shoulders and unlock it by rotating.
- Lower the bar along the guide under control until it grazes your upper chest.
- Press the bar up along the guide until your elbows extend.
- When finished, rotate the bar to re-lock it on the hooks.
Common mistakes
- Lining the bar up with mid-chest instead of the upper chest
- Forgetting to unlock the bar before starting
- Setting the bench too steep and overloading the shoulder
What the evidence says
Over the same 10-week program, full-range bench press produced greater strength gains than two-thirds or one-third range, even when strength was tested in the partial ranges themselves.

If you're after the upper chest, 30° of incline is where it's most activated; past 45° the work shifts to the front delt, while the mid and lower chest do more on a flat bench.

Between free barbell, Smith machine and machines, no differences in hypertrophy show up; what is specific is strength — training with free weights pays off when you test with free weights.

What isn't settled: Grip width isn't settled. What exists is single-session electromyography, not growth measured over weeks, and it doesn't even back the usual belief: a wide grip doesn't activate the pec more, it mainly lowers triceps and raises biceps involvement.
