Many people find the chiseled look of six-pack abdominal muscles appealing, but not everyone can afford expensive exercise equipment or a gym membership. Luckily, there are a variety of equipment-free abdominal exercises that utilize your own body and gravity as resistance. Follow these steps to get the sculpted midsection you've always wanted, without breaking the bank. Note that abdominal exercises like sit-ups help build muscle and do burn some calories, but do not target fat. To get a six pack without any equipment, first do exercises that target your lower abs, like leg lifts and torso twists. Next, work your upper abs with crunches and hip lifts.
