Help! I really want to run on a treadmill at the gym to help me lose weight. My problem is rather large norks (approx 36 HH). I have this sports bra www.bravissimo.com/products/lingerie/sports-bras/impact-free-sports/white/ro10wh/?criteria=sports+bra&show=16&sort=1 but, frankly I cannot run in it as it is not hugely supportive and I am still bouncing around all over the place (plus it's quite uncomfortable). Shall I buy another to wear over the top? Or do I get a cropped sports vest? Or something else? Thank you.
