Hi I'm running on a treadmill and am currently on week 7 of the couch to 5K. I do my warm up 5 minutes at speed 6 then run beteween 6.8 and 7 and have just introduced an incline of 1. I weigh mysefl before running then after and don't seem to lose anything plus I wear a sauna suit. Im trying to lose a stone in total. Feels like I should lose something the amount I sweat ??
