Hi here's the dilemma for me. I've just got tteesd with the Bruce test for total VO2, and even without getting to the very end, my doc switched me off at 13 minutes, which gives me a VO2 of 53. (I'm 42yo, female, 61-61.4Kg). In theory, my erg score should be 7'30 , but I the fastest I've ever pulled is 8'14 (!). Is this just strength I am missing, or what else come into play? I guess technique is one, but I am not completely bad (or so I am told). So what's the best training to get to that time? Thx.
