I didn’t join the STW chub club this year, but have been following a coached diet/exercise plan called The Sixpack revolution (hate the name but love the programme)
It is 75 days, and I’m 2 weeks to go. They tell you not to weigh yourself, as it’s about body shape and fitness rather than weight. Obviously I did though! So far 2 stone down and much fitter/stronger.
Basic concept is 6 meals a day of clean eating, with nutritionally balanced meals. Incrementally building daily exercises – started at 10 press-ups a day, currently up to 100 daily. Strength based not cardio.
I found I needed a structured programme and it has really worked so far.
