So when I wrote that I used 105 to 110%, I meant 105 to 110% of my concentric max. Is that enough to qualify as a supramax negative? I am doing these on squats so with a current max of 440, I'm doing one controlled but normal speed negative at 485, and one at 525 (and progressing) at the end of half of my squat workouts. I am squatting twice a week for two weeks, and once a week on the third week.
Since there are a lot of stabilizers involved, they may be near 90-100% of their limit even though the hips and thighs could handle more.
So is a supramax negative going to be anything above a concentric max, or is it closer to your eccentric limit, like 120-130%
As long as I'm over 100% of my concentric max, and adding 5 pounds to those 2 negatives I think it is helping me get used to handling heavier weights but I could use 485-525 with concentric from a high box as well, say 4 inches above parallel.
