Kelly Coffey-Meyer is great for 30 minute videos. She has a 30 Minutes-to-Fitness Series.

Good luck in your new hobby! I'm a home video addict - I have at least 300 workout DVDs.

I've never tried this specific DVD from Jari, but I notice it offers two different 30 minute workouts

I really like Jari Love's videos. Her workouts are longer than what you want (an hour +) but many of them can be viewed as shorter segments--for example her Extremely Ripped 1000 video you can do "cardio +weights" or you can do just cardio, or just weights.

Any favorite videos? I'm finishing up 30 day Shred now and there's a noticeable difference, but it's killing my knees, so I'd like to try something else after the 30 days.

30 minutes or less is all I have each day, but willing to do daily. Total body workout, not a specific area, as belly, hips, and thighs are all needing some tightening.
