I am thinking about purchasing a Cathe workout and need some info. Have been working out since 1984 and am currently doing the WHFN dvd's.I have enough equipment(minus medicine balls,stability ball/no room!) and don't want to invest in anymore right now.Lots of variety with dumbbells too.Need low-impact and WANT cardio/weights interval if it is available.Probably would be considered a beginner/intermediate exerciser with these although I am an advanced one for most other workouts.Are there any particular workouts you could recommend for me to get started with?Thank you ahead of time!
