I
highly recommend a sports bra with an adjustable shoulder strap and back hook closure. I know they can be expensive but it is
worth it, trust me, to buy a decent bra.
This is the bra I have currently and it is so good. I run/jog & also have done jumping jacks wearing this bra...Nothing moves or jiggles
. I do admit I was skeptical of the velcro shoulder strap adjustment part cuz I felt it won't be tight enough and well, may come apart while I run. But it stays on really well and hasn't once come apart. I've had it for couple months now. I think I got mine from either Target or Dicks sporting goods.
