Specificity is one of the four principles of weight training. Specificity means that you train your muscles and choose your exercises, weight, reps and sets with a specific goal in mind.
These goals typically fall into one of four groups:
- strength
- size (hypertrophy)
- endurance
- power
Depending on the goal, the nature of the exercise you choose, the weight, the amount of reps and sets, and the pace at which you perform them will vary.
For example, training for strength typically involves using a heavier weight that causes the muscle to fail at between one and four reps, while endurance training uses a lighter weight that causes failure at 15 to 20 reps.

Great Blog and very informative! Regarding supplements, after years of trial and error, and lots of $s spent, I now go with only three (1) MuscleTech Anator, (2) any decent protein supplement (I change it up) and (3) Acai Fire for Men. Protein Supps of course everybody knows about. Anator I found to be VERY beneficial after training for mass/muscle recovery; this can be found at all the ususal sources. Acai Fire is less known and my latest addition, and has been KEY in my view for enabling concurrent mass retention and fat loss. You cant find Acai Fire in stores but you can get a free trial by going to my URL. Highly recommend this combo and best of luck!
