Someone said: 30-day ab challenge. I just had to repin this because I've been doing it for only 4 days now (and at only 10 reps instead of 25) and already I'm seeing definition. And I've tried pretty much every Ab workout on Pintrest and haven't seen these kind of results.
Awesome Abs without Crunches: these moves work the transversus abdominis (deeper muscles that wrap around your trunk) as well as the obliques along your sides. Translation: a tinier waist, a flatter middle and sexy definition—fast!
