I highly recommend her dvd's! Especially if you have certain medical issues. (Always discuss Fitness/Exercise with your Doctor first!)
I have Plantar Fasciitis in both heels, RA and my left Achilles Heel Injury from last year (snapped while exercising) will flare up.
Fitted with the proper shoes, socks and paying attention to my body - Her work outs and outdoor walking are the best for me due to my issues.
I really enjoy her as well. She is so silly, funny, energetic and warm. She truly cares! (kinda like the female version of Richard Simmons!)
