Howie makes a good point about the water being in the legs a little by doing cardio so close...
Do what Howie says here, Mikey...hopefully TODAY was your last cardio day...but keep on movin'...do housework, laundry...go for a walk here and there...just dont be a slug the next few days. Leg training should be cut out say...7-10 days before a show.
Good call, HOWIE!
