I used to do Tae bo every night until recently. I kind of fell off the diet/exercise thing for a little while. But I did start to see results. My calves are smallier and tighter and so are my arms. I havent seen much results in my midsection, but thats my biggest problem spot so I know it will take time. As long as you do the tae bo and take in a lot of protein you are bound to see results.
