Only time in my life I've ever been serious about fitness was in the 2 years after my cancer treatments, 11 years ago. I was doing a lot of running then and did a couple of half marathons. In 2023 I've been gyming it ~3 times a week since July. I usually do ~35 minutes on the treadmill and then some weights and abs for 30-40 minutes. I started this because my wife wanted to join a gym and I was worried she might pull a Mrs. Creamy and "meet a personal trainer." So, I am on the treadmill about 3.5 miles with about 28 minutes of full-on running, I'm doing 5K in about 27 minutes. I've never had any formal instructions on how to lift weights or what to do; I really don't know what I'm doing but I'm definitely stronger. I lost about 14 lbs in the first 3 months but now I've gained back 8. I am guessing/hoping that is muscle vs fat but it's a bit frustrating. Especially since my Doctor said in November "You're on the wrong side of the upper BMI threshold and you should lose about 10 lbs. You're 45 now and need to start taking that more seriously." Also my blood pressure has gone up a lot in the last two years, but I have this weird pattern that my right arm is about 10-20 mmhg higher on the right compared to the left...wtf? Gotta study that a little bit more.
