I love "The Firm" workout videos/equipment. I have enjoyed them for years and have had great results. It is weight training combined with aerobics. There is a weighted sculpting stick, various step systems, etc. and there are A TON of videos which keeps your workout more interesting.
HOWEVER...I recently purchased The Firm "Wave" system (from an infomercial on TV) and I am returning it. It looked fun and challenging...but when actually using it...it is more of an accident waiting to happen (at least for me!).
Other than that, I LOVE all of The Firm stuff I have. I have seen some of it at Target...so you don't have to order from TV or internet. You can use any small dumbbells and don't have to purchase them from The Firm. (You can get the rubber coated ones very reasonbly priced at Dick's or Dunham's)
The Firm was the major reason I was able to lose my 40 extra "having babies" pounds...and I have successfully kept it off for about 5 years. In my world, diets don't work!Changing your lifestyle, eating habits and working out (especially with weights) makes all the difference. I found that once I started using The Firm, my metabolism cranked up and I could get away with allowing myself treats without paying for it later :-)
Good luck!
