Thanks. Since my post I stopped boot camp and LFT's returned to normal.
What liver disease do you have?
Strenuous exercise can increase AST and ALT levels.
"Elevations of the AST level may be seen in acute muscle injury, cardiac or skeletal muscle. Lesser degrees of ALT level elevation may occasionally be seen in skeletal muscle injury or even after vigorous exercise."
The most authoritative source for information about your own particular health status and how your should manage it would be your doctor. Talk to your doctor about your exercise routine.
Cheers!
