A regular yoga practice can prep your tummy for bikini season faster than banging out a million crunches.

In general, yoga is full of core-strengthening moves, but these stomach toners take top honors. They challenge your balance and stability and force your obliques, hip flexors, and even glutes to team up, helping you sculpt a seriously strong (and sexy) midsection.

Perform the following moves as a "flow" to raise your heart rate and torch more calories each session. Begin with Plank to Side Plank on your left side, then flow directly into Chaturanga to Plank before returning to Side Plank on your right side. Repeat the sequence, then lower to Forearm Plank. Rest on your knees for 30 seconds, then come into Boat into Half Boat. Repeat the entire sequence three times.
