While I work out in a group with Brannon, he and Gavin are very sensitive to the, ahem, "aging process." There isn't an exercise that can't be modified for my ache du jour. I am in a group of great women; our ages span from 40 - 66. I am proud to be the senior member and prouder still to get to the finish line at the same time as those who are my junior! Thank you NOS!
