I'm pretty lazy with the loading. For farmer's, I have a light, medium and heavy week.
My farmer's handles weigh 25lbs a piece, so for my light week I'd put on a 45 and 25 per side for 165lbs.
Medium would be 2 45s per side for 205lbs.
Heavy would be 2 45s and a 25 per side for 255lbs. As a 200lber, that's about the heaviest it'd go for a local show.
I'd go for 4x100' on the light days, 2x100', 2x50' on the medium days, and 4x50' on the heavy days.
Yoke was the same lazy approach. Yoke (supposedly) weighed 120lbs, I had 2 100lb plates and then the rest were 45s.
Light week was 410
Medium was 500
Heavy was 590-600
Same distance convention as with farmers.
Didn't really measure progress, just focused on keeping my feet moving quickly and speeding up the turn arounds. Since I train solo, trying to use a stop-watch was a cluster. Occasionally I'd video tape the sets and base it off that, but it was few and far between.
