I have done just about every fitness activity possible in this bra - Zumba, Kick Boxing, Step, Interval Training and Running.  It works great for every one of these activities. I have a larger bust (F cup) and this bra is far better than your standard compression sports bra. It keeps the breasts separated in their own cups and helps minimize bouncing during intense activities.  I love this bra with the exception of the straps.  For some reason the straps irritate my back sometimes and leave little scabs.  The weird thing is I don't even feel it when I'm wearing it andd only notice when I touch my back.  I will continue wearing this bra because of its performance but can't give it a full 5 stars because of the straps.  I would recommend getting a bra fitting to find out your size prior to ordering this bra online.  My size in this bra is different than the other bras I own.
