Yoga poses work by stretching your muscles. They can help you move better and feel less stiff or tired.
At any level of yoga, you'll probably start to notice benefits soon. In one study, people improved their flexibility by up to 35% after only 8 weeks of yoga.
Strike a Pose for Strength
Some styles of yoga, such as ashtanga and power yoga, are very physical. Practicing one of these styles will help you improve muscle tone.
But even less vigorous styles of yoga, such as Iyengar or hatha, can provide strength and endurance benefits.
Many of the poses, such as downward dog, upward dog, and the plank pose, build upper-body strength. The standing poses, especially if you hold them for several long breaths, build strength in your hamstrings, quadriceps, and abs. Poses that strengthen the lower back include upward dog and the chair pose.
When done right, nearly all poses build core strength in the deep abdominal muscles.
Better Posture from Yoga
When you're stronger and more flexible, your posture improves.
Most standing and sitting poses develop core strength, since you need your core muscles to support and maintain each pose.
With a stronger core, you're more likely to sit and stand "tall."
Yoga also helps your body awareness. That helps you notice more quickly if you're slouching or slumping, so you can adjust your posture.
Yoga usually involves paying attention to your breath, which can help you relax. It may also call for specific breathing techniques.
But yoga typically isn't aerobic, like running or cycling, unless it's an intense type of yoga or you're doing it in a heated room.
Less Stress, More Calm
You may feel less stressed and more relaxed after doing some yoga.
Some yoga styles use meditation techniques that help calm the mind. Focusing on your breathing during yoga can do that, too.
