air squats and pistols will likely be a good friend of yours in the coming weeks.
Also, use your opposite arm to do lightweight activities to keep your injured arm strong. There is significant data that shows that training movement on one side can help maintain/improve movement on the other. Try to keep it light to avoid asymmetrical stresses, however.
Working things like air squats and pistols will keep your growth hormones pumping and will actually help improve recovery time of your injured collarbone. Other suggestions include one armed dumbbell/kettlebell deadlifts, cleans, swings and presses.
DO NOT STOP TRAINING -- if you do, this will likely lengthen your recovery time.
Also, u can train low impact things like tuck jumps to silent landings, balance work on a very low rail and tripedal movement (its possible -- watch a 3 legged cat run).
