How much was on the leg press when you injured your leg? Did you shift the weight to one side to cause this to happen? What's you age range? I want to avoid what happened to you. Good luck with your continued recovery!
11 plates per side on the Hammer Strength 45-degree leg press. That's a weight that I could usually get 6-8 reps (and on a few occasions, I've hit 10 reps).
It also turns out that I was diagnosed as having patellar tendonitis (more commonly known as "jumper's knee"). In hindsight, I should have lightened up more than I did. It was on my final set when I got injured last year. That kind of tendonitis makes one more susceptible to tears and ruptures.
As for age, I was 52 then (53 now).
I’d worry about tearing your heart next
Why would I tear my heart, especially after having multiple physicals this year and last year (including blood work)?
