Tone from the inside out

“This routine will strengthen your innermost abdominals,” Miller says. First, you’ll do breathing sequences to awaken your deep belly muscles (including the obliques, the transversus abdominis, and, of course, the diaphragm). Next, you’ll incorporate the breath work into a few strengthening moves that will tone your core even faster.You’ll need a yoga mat, a handtowel and a few throw pillows or a small, cushy exercise ball. Do the routine 3 days a week, and your middle will become more defined, supple and sturdy, not just tight.
