Rule 8: the bench press, performed correctly, is a two-person movement. The spotter's hands must stay under the bar at all times during the movement.
By alternating which person is on the bench, a bro-training partnership can effectively work delts, pecs and tris (bench presser) and traps/biceps (spotter).
Top tip for spotters: don't forget to shout "it's all you" when it isn't.
230 strict press @ 220; bodyweight+187 X 4 dips @ 180; 403 front squat @ 210; 10 000 push-ups.
