anybody here try that workout ? Looks to be a real bitch-but also looks to be decent.I am a big guy-but LOVE crazy ass cardio /circut type of routines.Am too damn old to get monster big again-but insane cardio really makes me feel GREAT !!I actually did Zumba classes with the bride and was great.Sounds kind of gay-but lots of pussy to look at and that inspires the hell out of this old dawg LOL.Any of you guys/gals do crazy ass cardio routines ?Thanks-OD
