I spent most of 2019 and 2020 doing the lite variation of the Starting Strength method with no supplementation. Two days a week instead of three, and I didn't eat nearly enough to make the gains that I could have. I am a fan of the program. The beginning of this year, I stopped lifting and started BJJ. During the warm ups, I found I was barely able to do full push ups and sit ups, let alone the partner drill sit ups. Cardio isn't great, but isn't terrible either.
I'll agree with Doc Glock. It's not the panacea that I bought into.
I think there's a lot of value in a lifting program, especially for a sixty something individual. I also think it should be a supplemental activity instead of the main focus. If I had the last two years to do over again, I'd have started BJJ then, and done a basic lifting program on the side. Funny, I'm pretty sure that's what Cecil and Larry L told me to do all along.
