Guide to Choosing and Fitting the Right Sports Bra

Here is the guide to choosing and fitting the right sports bra

Sports bras were only invented in 1977 when two women invented a joggers bra by sewing two jockstraps together. Now there are several companies producing increasingly sophisticated models. 

There are two basic types: those which compress the breasts flat against the chest - which look like crop tops - and those which hold the breasts in the same way as a normal bra. As a general rule, compression-style bras offer enough support for women with breasts sized 32 -34A doing all forms of exercise and 34-36B for low-impact sports. For everyone else, the second type of bra is more suitable.

Some sports bras also come in different impact levels. As a rule, if you are taking part in lower impact sports such as yoga and pilates a bra with a lower impact level should suffice, but if you are practising higher impact sports such as aerobics, horse riding, jogging or squash you will probably need one of the higher impact bras.
