Is this a good workout?
Do I need to use dumbbells for squats? If so, how heavy?

Also i know that you need to rest about a day or 2 before you continue after a workout, from experience. I once worked my left thigh too much it caused me to have a muscle strain that hurt for weeks, I stopped doing exercises but now I really want to start again to get a toned butt. Any suggestions?
