Comments from people who have taken on the Fat Furnace challenge and won!

Group Support

I have done Fat Furnace twice and have been really happy with the results losing 11.5lbs and 11lbs. It is tough but with the support of the group, my partner and Craig I got through it! Doing it as part of a group really helped – if you like a challenge you will get through under the support and guidance of Craig but you must be organised and prepare your food. I would recommend both the programme and Craig.

Nutrition is the Key

I have participated in the fat furnace “challenge” twice now. My aim was not to lose weight but to help with my fitness whilst supporting my partner to lose weight. I found it tough at first but being organised with food buying, preparation and regular eating is very important. Craig was very supportive and helped with meal ideas. Others posted pictures of meals which was great to get inspired! I would recommend anyone to try this out under the guidance of Craig.
