I was introduced to the body shaping effects of lifting through yoga. A lot of my yoga routines uses body weight lifting and within 6 months [of daily yoga] I saw a total change in my physique. Very defined arms, noticeable pecs, abs. I've now moved on to incorporate more targeted body weight lifting exercises [since I have neither a gym membership nor weights at home] and found this site which for me is pretty useful in starting up a routine without any equipment. Granted some of this stuff is designed for men [pulls ups] but most of it is doable for women. Yoga dropped the weight off and gave me a base level of strength and fitness but a year on and I'm no longer seeing much change from it. Time to step things up, especially my lower body which has seen less definition from yoga than my upper body and core.
