Needless to say it was a worlds difference. About 3-4 months later, my bodyfat was down significantly. Why is this? Well for two reasons imo. 1) Your body adapts to the repetition scheme you work with, therefore if change the repetitions it is a different training method and your body must now adapt to it. 2) Higher repetitions equals more developed muscles and fat loss
Repetitions are very important, I suggest you start counting your reps! They determine the outcome of your training (along with MANY other factors). It is important for me to explain that you will not lose an ounce of muscle by increasing your repetitions. You will keep all of it, but it will start to show more.
3 repetitions or less -> Great for strength purposes, ineffective for mass or fat loss
5 Repetitions -> great for strength while still putting on a small amount of mass, ineffective for fat loss
7 repetitions -> Good for strength and size, somewhat effective for fat loss
10 repetitions -> the BEST range for size, decent strength gains, decent fat loss
12 repetitions -> Good for size, and good for fat loss, ineffective for strength from this point on
15 repetitions -> Decent for size, BEST range for fat loss, beginning at 15 repetitions muscle endurance starts becoming a factor
20 repetitions -> Ineffective at building size or strength, decent fat loss, mostly muscle endrance
30 repetitions -> Very effective for training the glycolytic pathway (muscle endurance), ineffective for strength, size, or fat loss
