👨👩👧👧反复练习，效果佳！Upper body workoutMike talks about a good work out routine for building arm and torso strength.💋Todd: OK, Mike, you are fit, and you got me motivated. I want to work out, so I thought I would ask you about a work out routine, so first let's talk about upper body? What should I do for my chest and shoulders?Mike: Well, the first basic chest work-out is the bench press, where you use the straight bar, and you should probably do three sets, if you're starting out: three sets, doing ten reps each set.Todd: OK, three sets would mean I do it three times with rest in between, correct?Mike: Yes.Todd: And how much time should I rest between each set?Mike: Maybe a minute-and-half, two minutes.Todd: OK, and then when I do each set, so you say I do ten reps, that means I lift the weights ten times?Mike: Yes.Todd: OK, and I should do heavy enough weight that I can only do it ten?Mike: Yeah, you should lift weight that is heavy enough
