Repetitions

It is often argued on what the desired number of reps(repetitions) should be when doing an exercise. The number may vary depending on ones physical goals or desires. There are plenty of ideas/opinions to follow including my own. My personal recommendation for general rep-range; If your looking to develop muscular endurance your exercise should involve twelve or more reps with a shorter rest period in between sets(I recommend 30 to 60 secs). If your main focus is strength your exercise should involve 6 or less reps with a longer rest period in between sets(I recommend 1 to 2 mins).
