Eazy Tip
 

Low weights and very high reps (Endurance training)

With this type of training you work mostly on the endurance of the muscles and some minimal muscle growth. The repetitions usually circulate in the 15-20 rep range, but sets of 25,30,50 and even 100 reps are not unusual for this type of training. You can implement it in your workout routine from time to time, just to keep your muscles guessing.

There you have it. Smart mixing of the three rep ranges will certainly produce more strength and muscle mass over time and give you the best from the three different worlds
