SETS AND REPETITIONS

Repetitions are the number of times you perform a movement from the start position to the final position.
Example: A biceps curl you start with your hands down,  flex your arm getting the dumbell close to your shoulder then go down to the starting position. This is an example of one repetition (rep).

Set is a group of repetitions performed consecutively.
Example: If you perform a biceps curl 10 times consecutively then put the dumbell down then rest and perfom again, you just did two sets of ten repetitions or 2 x10.

Resting time is your interval time between sets, during this time you allow your circulation to remove substances that cause fatigue from the muscles allowing you to perform the other sets .
Resting between sets is not necessary but I recommend.
