Now the excuse for a lack of exercise is due to poor bra design?  In what way is it someone else's fault for not providing comfort while moving your body to burn some body fat and building lean muscles?

She said: "There really are women who want to do exercise but who don't have the bras to cope..."

Oh come on guys, this is ridiculous.  To exercise is your choice.  

There is absolutely no excuse for not engaging in it, in one form or another.  Weight training and low (or no) impact cardiovascular exercises such as the stationary bike, stair master, or stepper are perfectly fine for any size boob lady to enjoy.  

It's reassuring to know that research is underway for those who experience pain or discomfort:

...Dr Scurr said: "We are building up a database on breast biomechanics which we believe is the largest in the world.

This information could be used to inform bra design, for clinical support, fundamental breast health research and to broaden understanding in this important area."

Amen.  But, until they build these super bras, invest in a few good sports bras, try wearing two at a time, or just hold your breasts in your hands (if you are in the privacy of your own home) while bouncing.

Because, where there's a will, there's a way. 

Just do it!
