Lab test results aet and ant or lt1 and lt2

    So I recently visited the lab on campus at the University of Texas in Austin. It is called the Fitness Institute of was very reasonable and they were very professional. My aet or lt1 was at 126 bpm. This was where my lactate crossed 2mMol/l . My lt2 or ant crossed 4mMol/l at 152 bpm. My max hr is 169. I have ads and plan on using the next 6 months to build aerobic capacity. The good news is that working out in zone 2 is pretty easy and will allow me to build volume rapidly. The bad news is that at 125 bpm I am basically at a brisk walk. Should I go 100 % in zone 2 for the next several months or would an 80/20 split between aerobic/anaerobic make more sense ? Any thoughts? Also I guess I’ve always trained too hard in the past. I’m going on faith that several months in zone 2 will make a strong positive change in my aerobic capacity. I expect to be able to go longer faster and still mostly metabolize fat as an energy source several months in the future. Is this reasonable ?

    Scott Johnston has talked about doing aerobic training (and holding off on the anaerobic intervals) until your aet is within 10% of your lt2. Looks like you are closer to 20% so perhaps it’s a good idea to focus on aerobic training until your aet rises relative to lt2.

    I wouldn’t do the 80/20 split yet.

    Thanks. So , over time, would my aet heart rate go up say to 137 , for example, which would be within 10 % of my ant ?

    That’s the theory. I would read the series of articles on aerobic training posted on this website for all the nuance.

    Thank you
