Based on the concept behind both Body Beast and STS, meso 2 is the only cycle to fairly and possibly be comparable. I have not completed a full Body Beast so
I can not make any review,Jump into any conclusion. I have had great result completing STS about 4 times. Looking forward to re-starting it later on this year. I have completed total Body Beast and could cope with/bare the speed, the intensity without any pausing
30 second from STS meso 1 --- endurance without pausing always feel no rest to me
. Triset from meso 2 keeps my heart rate high, again without any pausing. It also feel like no rest with the correct weight load selection. Plus it is fun.
