[QUOTE=Brian468;109867]What do they consider “high heart rate”? Im planning on applying to ECO once I get my STCW done, have no problem working hard but im definitely a big guy so i`m nervous after reading that.[/QUOTE]
The test they give is the “YMCA 3 minute step test”.
Google that phrase and you will get info on what the test is, how it is conducted, how it is scored.
There may be a “Y” near where you live that will let you join on a temporary short term basis that will help you with the test, or you can buy a heartrate monitor and assess yourself.
