Anyone else doing the swinging rope training as seen here:http://www.marksdailyapple.com/swinging-rope-training/

I've been doing it since last August three times per week with about a two month lay-off over the holidays. But I'm starting to get bored with the seven to ten different ones I do. Anyone have some new variations of this? Also, how many minutes do you do your ropes a week?

Thank you.
