Muscle Tone vs. Fat Loss
In order to reduce fat, how many reps range do I need to perform?
Hope to hear from you soon.
My Answer- Well you have 2 issues: lack of muscle tone and excess fat. To get muscle tone, you have to use heavy weight, low reps. To lose fat, on the other hand, you have to use higher reps with low rest periods. So you have to use a wide variety of reps in order to get a better physique.
The other issue you have is that you're doing cardio 3 times per week. At 6 feet, 150 lbs., you're in need of muscle. You don't need to do cardio, since the cardio is depleting your testosterone. If you want to lose fat, then use high rep strength training to lose fat. Higher reps (8-15+) coupled with low rest (30-90 seconds) will help you gain muscle and lose fat at the same time. Cardio just makes you lose muscle and makes you soft and "jelly-like."
So use a wide variety of reps to get both muscle tone and fat loss.
