No matter how many hundreds (if any... ahem) of sit-ups you do, you can't seem to sculpt your belly. In fact, you don't even wake up sore the next morning-- which is an immediate sign that you aren't shaping up your muscles. Instead of investing in an expensive gym membership just so you can use those electricity powered ab-crunching machines, go green and tone-up at home.

Exercise bands are a great way to intensify a movement. But not just any exercise band. Celeb trainer Linda LaRue's Core Transformer exercise bands are made from eco-friendly rubber and are all you need to get a total-body, muscle-toning, green workout. And here's the best part: They also help to cut your exercise time in half! Combined with the best abs routine, these bands work wonders. Check out my video below to see how it works.
