This is a question for me and my clients! How do you replace a 45-minute run (oops, sorry, all of you shouting “specificity!” right now. What do you substitute for a 45-min run?)
Climb stairs, check. Many mamas cannot do higher impact movements due to pelvic floor issues.
Do good cardio workout videos exist?
Christine Dwyer read my mind. I would also suggest Turbo Jam. It’s a little less intense than Turbo Fire, but still a great workout. It is what I used when I seriously started exercising but couldn’t get outside to run. It was from there that I got inspired to learn and teach Turbo Kick. I have Turbo Fire as well and it is also a great program. Whichever you choose, be sure there is always a modification available. Both Turbo DVDs have someone modifying the exercises all the time.
