I tried the balanced, heavy-on-stretches workouts, too.
Frankly, first, they bore me...all exercise bores me, except for a few extreme sports. Skiing down a mountain is fun. I hated running but I could put my mind in neutral and just let the brain-stem take over, while I listened to mp3 podcasts (back then I'd manually record Limbaugh or Jim Quinn, dead now, off radio streams) while suffering.
I can't do that with the complex stretches. I have to THINK. Thinking is no problem but it keeps me in the present, and the present, on a pad in the gym, is very, very tedious.
Nonetheless, I could do it. Until I developed back spasms, and calcium spurs on the inside of my shoulder socket. It's what gave me a torn rotator cuff. The doc says LIGHT exercise is okay for that arm, no power lifting; but something caused it to tear, and I don't want it to tear again, or tear more.
I still do one hour's power-walking. I can't do treadmills. First because I broke a couple while deployed in the Navy (at the time I was an eight-mile-a-day jogger; but new policy prohibited doing laps on the flight deck or the well deck). Even in military fitness, I was 230 pounds, and the treadmills of the time weren't up to that. On my last command, a carrier, I got permission to do laps with the marine detachment...they looked at my pear shape, and said, you gotta keep up, squid. I said, fine, and surprised them by doing it.
That was then. Since then, I've twisted my spine, got various arthritises; broken my hip, and my metabolism is seriously messed up. I blame my experimentation two years ago with Intermittant Fasting. I lost the weight but gained it back after I broke my hip, and now I'm eating half what I used to and I'm still too fat.
So. Ya do what you can. I like walking outdoors, but I don't walk as fast - and traffic in this town is a MENACE. A lot of that menace is deliberate - we have crazed, pot-addled Californitards everywhere. One just today, as I was walking into a sporting-goods mega-store...the dumb SOB aimed his Subaru at me, DELIBERATELY, no mistaking it, and then swerved away at the last minute. While making a left turn. I was already over in the lane opposing his flow; but he wanted to make a point.
So I go to the gym and do laps. One hour. About two miles. I don't know how much it's doing for my health - I'm not showing improvement, but it seems the trend is DOWN and I'm maybe slowing that.
