Join Yoga Classes in Udaipur HFS Healthline Fitness Studio http://healthlineudaipur.com/events.php By practicing yoga, the muscles are worked statically, concentrating on aligning the body in yoga poses. Using gravity to help with poses helps to ground yourself and keep your balance. Poses target different parts of the body for a varied muscle workout: the abs, back, arms or legs. Other poses like the warrior pose use all the muscles in the body.
