And even if you haven't got big bangers its a worthwhile investment anyway! Mine aren't big but they aren't exactly pert after two children so my sports bra stops them from flying all over the place and putting me off!! :giggle:
And I will be investing in a pair of decent running shoes when I've been doing it for a while longer, but for now money dictates I just use my bog standard trainers which are doing the job just fine. Sometimes it's worth investing a bit of time to see if running is for you before you shell out for all the kit! Having said that, I have just bought an iphone armband holder so I don't have to keep it in my hand!
The thing with the trainers is that some people can get away with cheap bog standard ones, and others cant - the problem being you don't know if you cant until its too late!
Last year (nearly 3 1/2 stones heavier) I started exercising for the first time in years (bar walking which I've always done). Was just going to a gym which had jogging stations in between the machines, but after a few weeks of going (and putting a fair bit of effort at the jogging stations) I found my lower shins/ankles were hurting on the inside of my legs. Went to a physio who told me I was flat footed and that I under pronate and needed decent running shoes to compensate (and my weight didnt help!) He also told me my walking boots were no good (I never replaced those though, and seemed fine). If fact he dissed all my shoes, and I ended up really annoyed that people get away with high heels and all sorts of nonsense, yet my physio suggested I needed sensible shoes all the time!
I think he was going a bit overboard to be honest, but I did go to some proper running shoe shops to replace my trainers - they analysed my gait (as best they could, I was still in pain when i went and stuggling to walk, let alone run) and I bought some brooks trainers which have an arch built in to counter my flat footedness.
Plenty of people dont have this problem of course and can get away with a cheapy pair from JJB, but it really is one of those things you wont find out until you try.
I'd suggest that if you dont want to invest in new shoes just yet, be really careful and listen to your body. If you dont get any problems then great, but if you have any twinges at all, stop and get yourself to a decent sports shoe shop to see what they say. My problem was, I felt the twinges, but didnt stop, and was in agony for a few weeks afterwards.
