Cassie, I personally do not have the belt for the 5 mile advanced walk. I just use the stretchy band again for that mile.
Unfortunately, I seem to be allergic to the stretchy band. I think it's the "powder" on the latex. I get it on my hands, and then I get it on my face, and the skin on my face starts burning nastily until I can douse myself under a cold shower.
I haven't mastered how to quote another person's message... I read one question about whether the WATP workouts are really intense enough or not. I find that the ones without the accessories can be made much more intense by keeping my hands higher than my heart the whole time. Don't just move your arms when Leslie says to, keep them moving throughout the workout.
Getting back into exercise after a year's falling off the wagon and countless inches put back on, I'm finding that walking with Leslie is the only workout I feel like doing. I'm glad for this option to ease myself back into this fitness journey.
