Hi there
I started the c25k in september this year
All 5ft 2 and 87kg of me
I don't think running the programme lost me any weight but it did kick start me into wanting a far healthier lifestyle. I was fairly active anyway, having done the 30day shred through the summer, but it was my lack of breath when running that shocked me too.
The pod casts whilst playing some pretty rough music at times, will give you some really useful tips on breathing and running style, a good one for me was to imagine you were running and walking behind a hedge and to stop you bouncing too much, a person on the other side of that hedge wouldn't be able to jelly which you were doing.
Also, if you haven't done so already, think seriously about going to a specialist running shop and have a gait analysis done and invest in the best shoes you can afford.
Wearing the wrong shoes can cause really serious injury.
Lastly, good luck and have fun!
I've just come back from a run, not using the podcasts anymore, but can do 4k in just under half an hour and loving my new energy []
