Non-weight bearing exercises needed

losingit4G

I have been non-weight bearing to one leg due to a foot wound and soon to have surgery and besides doing the Wii I haven’t been as active as usual aka doing 10000 steps a day, riding 12 miles on the bike and I don’t want to start packing on the pounds again-I’m down 20 but would like to lose 110 more. Any tips on getting good exercise in with only 1 functional foot?
