I mentioned that, indirectly. I've never seen training raise AST / ALT as much as OPs numbers though.
i had values exceeding 500 when ive done legs the evening before blood work or ALT/AST. GGT was in rage.
there are studies done on marathon runners where ALT/AST exceed 1000 the day after the marathon.
This usually goes hand in hand ith sky high CK values and more often than not microhematuria
