I'm a 65-year old female who definitely is not sprinting. But what I've started to do instead is nothing short of fabulous.<br>I started stair ascending and descending 44 flights of stairs a couple days a week within 14 minutes with many pauses. Each stair direction affects me differently, both in terrific ways. <br>The only measurement I can take at home is my blood pressure. Prior to starting it was in the 130s, high 120s over 80-90 diastolic. Since this way of exercising with the stairs, my blood pressure is in the 115/70's range. I was not on any medication before and now I certainly won't be.<br>Thank you for your content

I agree with the importance of strength exercises. I developed knee pain from injuring my lower back, after about 7 years, I was told I had 0 cartilage behind my knee caps. I couldn’t really run or squat at all. Just before the pandemic, a surgeon told me that in theory I should need knee replacements within 2 years, but if I would train and build my quads, there could be a chance I wouldn’t need knee surgeries at all for the rest of my life. Of course I trained my quads hard, doing asian squats everyday, I stopped doing cardio, only HIIT and long walks, now, 6 years later, I have no more problem with my knees anymore.

At 39 I was diagnosed with arthritis in the knees. I used to do marathons. I shifted to strength training and my knee pains disappeared. I now run periodically for a few miles at a time without a problem. Distance runners, as a whole, really should be doing a lot more strength training.

God, if only I actually felt better after exercise rather than 'It's finally over. I never want to do that again.'

Morning weightlifting is my routine. It fits my schedule. But motivation will fail you daily. Consistency is the key. Get a routine and do weak, do it tired, do it when you don’t want to. Just do it.

At 75 after losing 55 pounds I became a sprinter. I learned the hard way by tearing my right quadriceps. A few times and it was extremely painful! Now the running uphill 30 seconds times 6 to 8 and there’s absolutely no issues whatsoever.

OK, being a trainer I will chime in on the sprinting. Sprinting does not have to be super fast running. You can sprint on a bicycle. I recommend an assault bike. You can sprint on a rowing erg. You can sprint on a skier. You can sprint on an arc trainer.You do not need to be running to sprint. There are so many other ways that you can do your sprints. I love them on the assault bike because they really kicked my butt.

Wonderful discussion, Nick! This explains why some people struggle so hard to lose weight. It is much more individual than we gave it credit to be.

I do an exercise once a week on my exercise bike where I get my heart rate up to 190 (my max). It takes my about 25 minutes. I basically ramp up through the zones to warm up and then down like a pyramid. So by the time im at 12 minutes in, im doing zone 5. I dont stay at that zone, i merely reach it and immediately start to ramp down. This is not particularly stressful, but I consider it a minimum and makes me happy that I did it. Surprisingly, that 25 minutes once per week is enough to significantly slow down decline (in me at least)
