I've been on IntelliBurn since the beginning of the year and am thinking of switching to Inferno to shed the pounds a little quicker.
I started with Inferno, love love loved it! But it is hard! I have been actively working out 5 to 6 days a week for the last 10 years, I have done P90X, Jillian Michaels Body Revolution, and honestly Inferno was the hardest workout program I have ever done! It did deliver some amazing results, the best I have ever gotten! But be ready to get your butt kicked, you do need to be in a decently good amount of shape for this, or go try TBT first, then Inferno. Good luck! :)
