Metabolism-Boosting Core Workout

This ab workout does double-duty in the flat-belly department: not only does it target your core to help define ab muscles, but it also builds muscles all over your body, which helps rev up your metabolism to burn more calories throughout the day. Get the workout below and print it out here.

Quinoa Cabbage Salad

Don't be put off by the "salad" description; this warm, wilted cabbage and quinoa dish makes a light, comforting dinner that soothes tummy issues. Each ingredient helps digestion, and the fiber in the chickpeas, cabbage, and quinoa will help you debloat. If you'd like, add a dollop of Greek yogurt for a creamy element and a dose of belly-helping probiotics. Get the recipe for lemony quinoa cabbage here.

Yeah the same! I have been doing 15 on each side with the exception of the runner lunge with press up, elbow plank with reach and the elbow plank with rotate as I find these extremely tough to do more of. Gonna try build up to do 15 each side tho! Any advice fitsugar??

I would like to see more pics for some of these moves. When you say 15 reps, does that mean 15, alternating sides, or all on one side, change sides on the next repeat? I like these workouts, but some aren't very clear.
