Quadriceps tendonitis. Recovery time seems to be 3-6 months, but some people are saying they've had it for years. Am I fucked?
From what I've been learning with my biceps tendinitis, is that isometrics are key. Start with the lightest weight you can handle, or even bands, and hold a leg extension aiming for around 30 secs. A few sets of those a day, really dig into the part of the motion that causes you discomfort, and you'll see improvement.
Dont push it to the point of causing significant pain, but dont be afraid of it either. Often, youll see immediate relief but it will take days and weeks for the pain to fully subside. From my understanding, rest does not improve tendons. It needs to be strengthened.
Supplementing collagen peptides has also made a huge difference. After two weeks being out of the gym, I spent a week doing isometrics for my bicep and shoulder (front raises, laterals and curls) two to three times a day, plus taking two tbsps of collagen twice a day, and made it back in the gym today.
The tendons are still a little sore after that workout, but definitely not anywhere near where they were originally.
