i like the exercise that gets something done or makes something, win win for sure,, I try to use hand tools as much as possible for that reason,, pulling the bow to get it tillered sneaks up on you too,, I have not cut much wood in a while, but that is more than a work out,, those osage logs are can be challenging mentally and physically,,  

 they can break you hammer ,, your wedge,,, your chain saw or your truck,, 

 really when you get a nice stave in the mail,, 90% of the work has been done for you,,
