I want to hire a machine to use in between school runs etc. I run outside at the mo but will find it harder during winter when it's dark. I will still go outdoor running when possible though as I love it. as I have a busy daily schedule and want to lose weight would it be better for me to get a rowing machine or a treadmill that I can do 30mins am and 30mins pm and also vary the programs (hills, sprint etc)????
I really want to do proper training as I want to enter a full marathon. I have done 3 half in the past.
