Cool if son want to stay healthy and fit.
But that smith machine is a no no for benching(ONLY AND I MEAN ONLY time I would fukk with it is for shoulder presses. For the simple fact I hate the way they have the barbell press set up). He should start of with 1 plate(on both sides) on the bench and work his way up. Plus like
@Pop123 he needs to hit the tris hard. That will help him get his bench up. Also those reps don't count unless it touches his chest or at least close to it.
But spotter for smith machine is by far the funniest shyt I ever saw b

only a gym rat could find the comedy in that.
