Last week I was on plan every day and lost 2.5lbs, My normal daily routine involves a lot of ins and outs for school runs, clubs, baby group etc, and then extra exercise included 1 walk around a local park - about 1.5 miles. This week I was on plan every day, my normal daily routines, additionally; park on sunday 1.5 miles walking with the kids on their bikes, then again Wednesday from school > park > back to where I left the car at school - about 3 miles total. On top of that we now have an exercise bike which I did 3 x 5 mins the 1st day it came, 3 x 10 mins, 2nd day, 2 x 15 mins the 3rd day, then 2 x 20 mins day 4, 2 x 30 mins day 5 & 6. Yet I went to weigh in last night and had only lost 2lbs. I was expecting more because of all the additional exercise. Why wasn't it?
