Now rep is short for repetition. Repetition is basically one lift of an exercise is rising away it's a, it's doing a bench press, doing a leg extension just one movement is one repetitions, usually you want to do somewhere between 6 and like 15 or 20 repetitions and that's another thing with variety you don't want always do the same number of repetition you want a kind of change and upload it. Sometimes do lower reps sometimes do higher reps and then one set is one grouping of repetition. So say the two sets of an exercise that means you have done may be 10 repetitions that's one set you take a break and come back and do another 10 repetition's that's another set. You have done 2 sets of 10 reps or repetitions.
So when you do this and you may want to start with a little bit of lighter weight first and not that condition that you haven't been training and your body there is a inverse relationship between intensity and duration, you want to kind of keep the intensity a little bit lower and may be do a little bit more initially, just as you get your body used to the movement you don't want pile on the weight and do a high weight lower reps set, you don't want to put on you know twice a way you can handle when ever I do four repetition may be do 10 or 12 the start with may be in 15 then as you get stronger sometimes you can do sets, of a lower numbers like 6 to 8.
Once though I can flow in a real soccer and do like a century set really light weight and do like a100 repetitions. But the key is just keeping a variety to the repetition's is not having a target number per set either you don't want just shoot for 15 reps and stop when you get there, you want to get to the point works basically almost in possible freedom move and that's when you start. As long as you can safely and carefully do that. As far as sets go that's really not that much reason to do a lot a sets or like if you do three sets of an exercises I do three sets of bench press and I am not necessarily going to get three times a benefit. The most of the benefit comes from the first rep the first set.
Almost 50, so it comes from a first set and that's what in home many users may feel you just do little 7 exercises one set of each you are going to get most of the benefit. If you have time and you want to additional sets, or do like a warm up set and then I have your set that's fine with me too.
