I dare you to try this workout!! This is from Jamie Eason's LiveFit 12 Week Program and I never leave the gym without Jello Legs after I do this workout. Make sure that you use the right amount of weight. You should barely be able to do the 10th rep with good form and not be able to do an 11th. If you push yourself hard like that, & the way the program is supposed to be, you WILL have jello legs! & they'll be sore for days! :D I DARE YOU to try it out!
