For individuals attempting to achieve fat loss for
aesthetics, the intensity of weight training can be a double edge sword.
When beginning an exercise
program, muscle mass increases may out pace fat losses, resulting in a small initial weight gain.
Significant fat loss requires a certain intensity, duration, and frequency that novice exercisers may not be able to achieve until they develop greater tolerance to exercise.
If an exercise and nutrition program is not adequate for significant fat loss, a lighter weight with higher repetitions may be recommended to minimize any bulking effects, although less fat may be utilized hours later.
If an aerobic exercise and nutrition program is sufficient enough to lose fat, a
moderate repetition range with a progressively heavier weight will accelerate fat loss with a toning effect. If a muscle group ever out paces fat loss, the bulking effect is only temporary.
For a toning effect, fat can be lost later when aerobic exercise can be significantly increased or the weight training exercise(s) for that particular muscle can be ceased altogether. The muscle will atrophy to a pre-exercise girth within months. Higher repetitions training may be later implemented and assessed.
It is plausible that the high repetition myth was originated and later propagated by
bodybuilders that used calorie restrictive diets to shed fat before a contest. Because of their weakened state from dieting, they were unable to use their usual heavier weights.
When inquired about their use of lighter weights, they explained they were "cutting up" for a contest.
This is merely a theory, but it is easy to see how it may have been misunderstood that the lighter weight was used to reduce fat instead of actually being a result of their dietary regimen.
Typically with weight training alone, fat loss is similar to muscle gain, give or take a few pounds.
Certain dietary modification can have much greater impact on fat loss than weight training alone.
The ideal program for fat loss would include the combination of proper diet, weight training, and cardio exercise
