Body for Life - Weight training

Yesterday evening I did the lower body weight training of the Body for Life program. I put together my workout according to the instructions on the website (I have still not been able to get a hold of the book). It contains 4 muscle groups with 2 exercises for each. You can find a detailed description here.
After the workout I found that I had not given 100%. Eventhough during the training I felt like I did. Especially during the Hamstring exercises. I will try to push more next time for two reasons:

1) The legs are my problem area (cellulite).
2) The legs are big muscle groups and if I build some muscles there I will burn even more calories during the day.

My gym offered me to program the machines according to my plan. Which I thought was not possible. But I am even happier now that I know it is. I just need flexibility with the weight. I am still trying to find the right intensity and don't want the machine to tell me "You have chosen too much weight". Supported training is good it should just not be restricting.
