Sets, Reps....what to do??

Strength Training- Also known as resistance training, is muscular contraction to increase strength.
Reps- Short for repetitions, is one complete movement through an exercise.
Set- Is a group of reps.

A lot of people get all "bent out of shape" over how many sets and reps to do, but don't waste too much time or energy on this, spend that on lifting!  For weight-loss and general health I usually recommend 8-12 reps and sets of 2-3. Giving yourself a range of 8-12 will help determine what is the best weight to use. If you are unable to do at least 8 reps WITH GOOD FORM, the weight is too heavy. If you can do more than 12 reps WITH GOOD FORM, the weight is too light.

This means you may be changing your weights before the next set or depending on how you feel for a particular day. For example, if you have a lot of energy one day, you will be able to lift more and should to get the benefit. If you feel tired/weak one day you will need to lower the weight in order to keep proper form.  Keep in mind the immediate goal of strength training is to fatigue your muscles, NOT do the most reps or sets of an exercise. This means you don't want to "save" yourself to do extra sets. Challenge yourself with the set you are currently doing, if your muscles are okay to do another set after then great, if not then even better, that is the point!

REMEMBER- FORM IS KEY!
