I'm so unfit, overweight by about 4 stone and about to hit my mid-thirties. I used to love exercise DVD's pre children but have lost my way. I bought Davina's 30 Day Fat Burn today and gave it a go this afternoon. My thighs are killing me! I'm really up for challenging myself and committing to the 30 day routine. Does anyone else want to join me? Has anyone else completed this? How did you find it?
