To lose 1lb a week, on an average day you should burn around 500 calories more than you eat. You cannot target specific areas, eg belly fat. You can tone muscle but fat/weight loss means overall body weight reduction. To burn this with Hatha Yoga will take around 2 hours 20 minutes ever day for a week. Ashtanga or Power Yoga would need around 1 hour 30 minutes daily. For most of this just isn’t practical. Hot Yoga or Bikram Yoga fare a bit better needing just over an hour but the best choice is Vinyasa Yoga or Yoga Flow at a little less than an hour.
Those figures are average for all weights. Calorie burn varies with many factors but weight makes a big difference so check below for calories burned by weight. The calories below are for an middle of the road yoga class. For more accuracy choose your yoga type here.
