Absolutely. I just wanted to get the facts straight that VO2 max is absolutely the most important thing. No reason to not just do everything however. Reaching the point of diminishing returns for VO2 max and strength training is not that difficult and is even easier to maintain than it is to gain.
I have been incredibly out of shape and overweight most of my life. In the last year I've managed to lose a lot of weight and I started weight training about 8~ months ago. I saw my VO2 go from 33 to 39 (which is still quite low) at a very steady rate and then all of a sudden just plateau at 39. Was absolutely annoying because I thought I had only a month or two left before I hit that 50%/Absolute Average point for my age :(
Sadly (for me), I think this means I actually have to start doing cardio.
The point of diminishing returns for benefits to longevity is reached after exercising a couple hours a week for a few years consistently. Then you just need to maintain that. VO2 Max itself can still improve over time but the effect on longevity is not as significant.
Also, strength training does not necessarily mean benching 3 plates. Also it does not mean 0 cardio.
