You're probably under the (false) impression that building wads of Hulkish muscle also requires wads of cash, because most muscle builders have complete gyms filled to the brim with weights and tabatas.
But you can train and get lean at home with just one simple and cheap tool: furniture sliders, available at Lowe's for about $9.96. For under $10 you can use these sliders to do sliding push-ups and other creative moves. Watch this video for the how-to.
Some other exercises:
* hand walking for distance or time
* push-up pike-ups
* push-up reaches in all directions
* ab roll-outs
* backward lunges
* glute bridge in hamstring curls
* quad squat into sit-through push-up
