Ideally, wear a commercially made binder with compression fabric that is on the front of the body and a looser fitting fabric across the back (rather than the same tightness of compression all the way around).

Massage and stretch your body after each time that you wear your binder.
Practice deep, rib-expanding breathing when your binder is off. It will help you to have better capacity to breath when you are wearing your binder which will make wearing it more comfortable for longer periods of time.

Work out or play sports in a less compressive garment than you wear regularly. Sports bras are designed to promote movement better so if you are able to wear a sports bra and a baggy shirt, that is a great option. If not, wear a binder that is a size larger than you need or an older binder that has stretched out.
Learn the warning signs of serious problems and don't mess around if you experience them. Get the binder off immediately and get to a medical professional if the symptoms don't go away promptly.
