Just wondering about heartrate. Should he shoot for 80% above to twice his heartrate? Once again, I heard that it is only after 20 minutes at a high heartrate where you really start to burn fat.
The thing is the internet is full of fads, false information, and information and sorting through all that crap is a pain. It is actually helpful to have somebody as knowledgeable as Plan 9 whose information is trustworthy.
