How about swimming?

  In my experience: Hard to max out your heart because you are always oxygen constrained when front-crawling. I did high intensity breast stroke for 1-2 months each day, instead, and suddenly developed terrible back pain, so that does not seem like a solution either, but it might also be due to my subpar technique.

    Sounds like we have a similar problem: start doing something and immediately do it very intensively and cause more harm than good to your body. High intensity + each day sounds like a bad idea almost always. The only people who do it with a good reason are professional athletes and they still have injuries all the time
