I have been working out with Rohit at MFB since November 2011, and I have been able to transform my body in about 3 months, by losing a stone and a half (10 kg) whilst gaining muscle and body definition.
I have been a member of most of the major-chain gyms for the last 10 years, but going to the gym never yielded any results, as I discovered I am just not able to motivate myself to perform constant, vigorous excercise that has one's pulse always at around 80% of max and leaves them without breath, for 60 mins.
Rohit's classes have always been different and varied, which also helps to avoid falling into a routine.
Yes, they are tough, but my word of advice is - there aren't any short-cuts to weight loss and body definition...
Nowadays, I always go for two hours in a row, doing suspension training and circuits followed by body combat with Rohit.
