This guy knows.
Although it does not take 7 days to lower them. Through experimentation, I have found that 4 days of rest, no lifting, no cardio, is sufficient.
Bigbicep, seriously, take some time off of lifting and retest. My doctor had me all signed up to go to a liver specialist. I was freaking out thinking I had somehow killed my liver. I was researching online and discovered that this was extremely common in athletes. Moreover, these markers are not like other markers, where being slightly out of range is an issue. If there is real lover disease, these markers will shoot way up higher than your results.
So I took time off.
Now I almost always take a break from the gym just so that these numbers will come back in line.
If you do something physical that is intense, if you are sore, new cardio, anything, you will throw both these markers high.
Take a break and retest and let us know.
