Best results in muscle definition have been with STS - hands down. I'm waiting for Cathe's November rotation because she said she'd incorporate the new ones. I've done one a night since receiving them on Monday, just so I'll be familiar with them. I'm really loving every one of them so far, but I can already tell that I'll want to sprinkle them through the week & not just do LIS every night.
Hmmm...Well going back I have a few rotations that I got great results with. I will list them in time order, starting with the earliest first....
1) P90X back in 2007
2) Insanity in 2009
3) STS in 2011
4) Body Rock in 2011
Obviously my body prefers odd years! LOL
As for LIS, I don't have any specific plans for it yet. Going to start trying them out this weekend. Once I've gotten thru them all (which could take a while since I'll probably only do them on weekends), I will decide how I am going to utilize them.
I'd have to say STS with STS cardio - man I couldn't believe how much my body changed from those workouts! When I did STS weights & STS cardio - it was my 3rd time doing STS and I don't know if that had anything to do with my improved results or not. I think it probably was more the incorporation of STS cardio - those workouts really complimented STS weights so well. I didn't lose that much weight on the scale - but by the end of STS I was wearing size 4 pants that previously I fit into when I was 15 lbs lighter...it was wild.
I am just finishing up my 4th round of STS - doing the 5 1/1 month rotation (which I LOVE by the way) and am really looking forward to a 5th round of STS with LIS and STS cardio. I think that will just be the piece de resistance of workout programs!
