as title says
gonna be a reet fat wap if i don’t do somet,in this period off biking and work.

Turbo trainer? Flat pedal for the cast and SPD on the good side. Dull, but it worked for me in that situation – and stopped me losing the plot through lack of exercise.

Climbing worked well for me when I busted mine. Very low level traversing back and forth across the local wall, builds great stamina as well as core.

Mine ached like **** every time I stood (or even sat)up, all I could do was lay around with my foot up for six weeks
