micoach is all you need to get the results you want.
I do track and field and I got this sports bra for that. I'm a size 34C which makes me a size 37" chest... I got size M for this sports bra. I like it, it fits like all the other techfit bras I have. My only complaint is that I wish the part that holds my chest were a bit tighter and more supportive. This is a pretty straight forward, standard sports bra but I wish it were geared a little more towards higher impact stuff.. because it looks (by the amount of fabric) that it would have a little more support. The band is nice and tight and fits, but it's not as tight on the chest as I'd like it to be. I've tried on a small and the band is WAY too tight, but the top fits more like I like them to (nice and tight, and secure). But overall, for the price it's an amazing bra. Hard to beat.
This bra was great for lifting and training, but not the best for cardio. If you like a looser fit for cardio, then this sports bra would probably work for you. I prefer a more fitted bra that works for cardio and training. It was made of super comfortable material however.
I am a runner and MTB gal and this bra ensures no rubbing even on the hardest of trails, with plenty of sweating. 10 out of 10 as I have had other brands that I simply had to throw away as too uncomfortable and chaffed me. This is my third repeat purchase!
