I'd love to have some more boxing workouts, besides Contenders' Club and Aerobox. I like to have an upper-body-focused cardio option (and be able too use my Wavemaster punching bag some more).
I'll have to see how this current batch of workouts turns out (the same music volume and bad chaptering problems as in the HC's?) and have more details about the boxing workouts (if there are just a few boxing moves thrown in with lots of cheerleader jumping blasts, I may pass on all of them).
