Hi Kelly,
I have been doing it for 3 weeks now - there is a huge difference in my ability to bend and run and I can do the push ups now - I a getting stronger and have lost inches - I still have a long way to go, but I truly like the program and plan to stay with it to day 90 ad beyond. I use 5 pound weights and take their fat burning vitamins as my vitamin supplement. I bought the resistance bands,but I like the weights. I like the DVD, but I also have the Videos. If you like structure and something that is challenging yet doable as well as fast - they have a motto of from power to shower in under an hour. Let me know if you have any other questions. I see that you have been doing well on the Atkins plan - keep it up!
