No matter the style of yoga you choose — hatha, vinyasa, or hot yoga — nearly all of them include a few key moves. To stay safe, your best bet is to work with a trained instructor who can show you the right way to do each position. If you’ve had neck, back, or joint pain or flexibility problems, talk to your doctor before you start a yoga routine. Most of all, don’t push yourself to do anything that hurts. You can tailor most poses to work for your body.
