It's fine, I've heard of people wearing two sports bras, or a nursing bra and sports bra on top. Go running right after you nurse or pump so they are lighter, it'll be fine
I haven't had any problems but unfortunately I only go running once a week right now. When I asked the dr. about running she said it was ok as long as i eat and drink enough. I wear two sports bras- that really helps.
Under Armor is the BEST it is pricy but worth every penny. Get the high impact tank top or sports bra. I can do jumping jacks, run, or whatever we have to in bootcamp (the workout kind not the military).
The Ta-Ta tamer from Lululemon is amazing! It's made for
larger chest & mine doesn't budge when Im working out.
It's a bit pricey, but absolutely worth it
I wear 2 fairly loose sports bras, so I have support for my boobs but not so tight to avoid clogged ducts, etc. I'm not very big, though; if you need more support, I think they have some on LLL's website.
Re: Any runners out there?
My boobs hurt too much to run, ever, while bfing. I'm sure some can do it, I just couldn't.
