The term "body sculpting" essentially came into the mainstream vocabulary in the early '90s with the success of The Firm home workout videos. These videos mostly targeted the female market but they did have some success with men, though most of them wouldn't have admitted it around "the guys." Still, a good workout is a good workout regardless of gender.
If you're a guy and you're ready to put aside preconceived notions about the idea of body sculpting, you can make some tremendous gains, particularly in your mid-section. You can also look for cool sculpting at Dallas prices for fat freeze treatment.
For starters, it's important to note, most women will shy away from adding any resistance or weights to their ab workout. This doesn't have to be the case, in fact, I would encourage you to begin adding weights or using resistance bands right from the start.
This means you will most likely (if you've added enough resistance) not be able to do the same number of reps, but that's fine. By increasing the resistance and decreasing the reps, you're going to cause your muscles to increase in mass quicker than doing this without any weights.
If you're worried about your waist actually getting bigger than it is, don't. Your muscles are going to reach a maximum volume and you're not going to be able to make them grow to an abnormal size without artificial supplementation.
