5.0 out of 5 stars Intense? Yes!!!!, March 17, 2002

By A Customer

This review is from: Nac System: Interval Challenge [VHS] (VHS Tape)

No one has really described this video, so I will try.... :). This is approx. 45 minute floor hi/lo impact aerobic work-out. No dancy-fancy stuff. Beginners and advanced exercisers can do this workout by following certain instructors throughout the video. There is a warm-up/stretch, 2 minute hi intensity followed by 2 minute low intensity to get your heartrate down workouts (repeated 5 times) then a calming cool-down/stretch. Also, there's an little routine that the instructors which they say is a sample of what national aerobic champions' routines are like. They teach you this routine about 2-3 times and do it for you. It's just for fun.

I personally enjoyed the video. i like interval training and this gets my heart jumping with those pylo jacks, side lunges, step-up jumps, jump-rope jumps (watch David do this at one of the last intervals. wow!) etc. The 5 instructors are National aerobic champions and are very encouraging throughout the video--they tell you that it is important to slow down during the low interval, and that when you cant keep up, do slow down, etc. They arent like the loud "whooping" Crunch exercisers and are more enthusiastic than the Classic Firm instructors. The music is satisfactory and goes well with the certain routines.

In essence, this is a refreshingly aerobic workout all the way and is for those who enjoy "athletic" moves.

Also, I think every video has a free booklet that tells more about the NAC program and about max heartrate, schedule of videos to alternate etc. Personally, I didnt find this helpful.

5.0 out of 5 stars Perfect way to burn calories., December 9, 2005

This tape is perfect for intermediate/advanced folk. Five National Aerobic Champions take turns guiding you through an aerobic routine that's based on "intervals" - moving from low-impact/medium pace routines to high impact very intense routines (that last about 2 minutes). Interval training is trendy right now because exercise gurus say it burns more fat than exercising at a consistent pace. There is a lot of hopping and jumping that will turn some people off, but two of the instructors stay low-impact (no jumping one foot on the floor) throughout the tape - so you don't have to go high-impact if you don't want to.

I'm not very coordinated, so it took me about 5 or 6 tries to get the harder moves. The hosts direct well, and are upbeat without being annoying. My single criticism - they don't incorporate much pre-exercise stretching. You'll want to do your own stretching, with emphasis on the legs, before starting. The post-routine stretching is adequate.

This workout is outstanding. I have been an avid tennis player for 30 years. I used this
tape to get "in shape" for the tennis season, as I only played doubles in the winter time.
I have my favorites on there for sure.....but I have never tired of it. I am still doing it
5 days a week, or on the days I am not playing tennis. I am 66 years old. I accredit that
the NAC system.

I wish there was another one out there. I need that anaerobic intensity.
