Fitness for old fat sdratsab
I've mentioned before that I've been doing a bit of strength training and some beginner crossfit stuff in addition to hiking. I try to do extended hikes one day, followed by the strength and crossfit with a 2.5 mile walk the next. These are by no means major workouts. They're just my attempt to work getting back into shape into my leisurely schedule.
Today I did bench press and curls and sit-ups, followed by one of the homemade pseudo-crossfit exercises I've developed which is to flip a tractor tire over a bunch of times. Followed by the 2.5 mile walk.
The tire weighs 185 kg or 407 lbs. It's 1.73 meters or 68 inches in diameter.
Using the law of levers I can work out that I'm lifting just over 123 kg or about 272 lbs and the force required to do so is about 213.345 Newton meters. So in a very loose sense I'm lifting 213.345 kg or 470 lbs for each flip.
I do four sets of six flips plus one more flip to make 25. I do it as quickly as I can, which isn't all that quickly, but comes in at about 45 seconds per rep for a total of three minutes, give or take 10-15 seconds.
This is a really good anaerobic workout, at least for an old fat guy. It makes my heart pound like a trip hammer and it takes a good 3-4 minutes to catch my breath.
So on the one hand, I'm pretty strong. Always have been. Any fat guy has to be strong to haul the lard around.
But strong isn't everything, and it's not got a lot to do with fitness.
It's a work in progress. But at least it's in progress.
You really don't realize how fat you are until you see yourself on the video.
