exactly. In regards to the upper back triceps example. For instance, I started with sears weight set . 110 lbs. I added metal York weights, a better exercise bench. Capacity might have been 400 or so total pounds btw.
I had 200 or so pounds of weight. I was benching 205 at 132 and 16. I was deadlifting 205. I was squatting 110 for sets of ten. I had to clean and press the weight . Squat it, then push jerk it off set it down , repeat
I was a stronger bencher . When I went to college I worked hard to bring up the sq and dl. Now I was weighing 142 and benching 215-220, deadlifting mid 300s and squatting low 300s . I had to cut weight to make 132 and lifted there for a year . I did official lifts of 340/230/360, maybe 235 leaving some on the platform that day . It was the state championships for teenagers and I had it won on openers and had no drive that day . This was in one federation days btw.
But I digress . My point is I did what I could which was a lot of upper body. I concentrated hard on my sq and dl when I could , but my bench lagged then . And back and forth . Many of us will go through this .
You go from 130-210 and your squat , desdlift, and bench form might change . Just due to different proportions. When I was 132 I had great squat form . Now at 200+ I don't think it's as good snd I point the finger at box squats . I knew below parallel like I knew scratching my nose. Now i've had to concentrate on depth again at a heavier weight .
It all adds up to where you're at. Training in sn organized fashion is never wasted .
