Riding long mileage on the coker

Hi,

I got a coker a few months ago and started riding some long distances greater than 25miles. My legs are fine BUT my back is so soar. (expecially after riding cambered roads)

Any back strengthening excersizes to recommend? Any other recommendations?

Thanks.

Reverse leg lifts

Reverse leg lifts will strengthen the muscles in your lower back. Your abdominals work to support your back during the exercise. Working both back and ab muscle groups makes this exercise great, if you have a healthy back.

ride backwards half the time to even out the camber overall : P
