How to do a Bench Press
The bench press drives a loaded bar or dumbbells up from your chest to build the chest, front delts, and triceps. Good form lowers to the chest under control and presses to a full lockout on a steady bar path. CalmArms films from the side and grades every rep A–F, hands-free.

How CalmArms grades the bench press
CalmArms grades how far you lower to your chest, your press to lockout, tempo, and whether you hit the bench angle you chose. Dumbbell sets also grade left-vs-right evenness; barbell sets ease up on that since the bar locks your hands together.
