I have to say, DS recently got his cast off for a fractured elbow and then had 2 more weeks of reduced activity (so 5 weeks of mostly only conditioning). His coach was telling me just today that he is doing better now than he was before the cast (he has been back for about 1.5 weeks at full workouts). I think all of that conditioning definitely helped him!!
I hope the break isn't too bad. DS fractured his ankle back in the spring (both of these have been playground injuries!). It was fractured at a growth plate; but it is apparently a growth plate that most people don't have, for an extra bone that he has in his foot (we found out that he has 2 extra bones). He was in a boot for 3 or 4 weeks I think, then 2 weeks of reduced activity.
Now that I think about it, this poor kids sure has had a lot of extra conditioning this year. LOL!
