Hey Randi,
Do you have a Dyna-band or does your gym have them? If you do, then I know two really great legs and butt workouts you can do with them. The first one targets the whole leg and butt, it doesn't have a name, but I'll explain it. Ok make sure you have a pathway or a large room you can move across. You tie the band at your calves, not too tight but not too loose. From this point you stand in like a squat position but not too low. Here you turn sidways, and step out with the first leg in front, then move the other one in next but don't bring them togather, you wanna keep that high squat position keeping the knees bent at all times. If you can do 2 laps with these going up and down the room or path, you but and hams will BURN}(. i hope I explained the well. The second one is easier (to explain not do:7) You need to hold on to a wall or something to do this. You keep the band tied, but yu put one part underneath your foot and the other one where you would have shoelaces. (you may wanna wear sneaks if you can, or the band may not stay) From here, the foot that the band is underneath you curl that leg up to target the hams. Do as many as you can and however manys ets you want. sorry this is so long.
Good Luck!
