I think around April/May most people's slowed motivation from New Years starts up again in time for the beginning of summer. Maybe its just me. I find the 30DS to be one of the best workout starter uppers because its intense and short! Exactly what I need to begin getting fit! The whole tape is about 20 minutes and it teaches you to push your body, I'll admit I've never done 30 days in a row but doing this tape a few times definitely helps train me to be more efficient at the gym. I actually see my workouts as more of a race-20 mins here, 20 mins there rather than "seeing how long I can go" at least for me when theres no end in sight I give myself a break on the intensity so putting a time limit on things help to push me hard! I have a goal of 20 pounds by Labor day! I'll keep you updated!
