I'm currently stretching the tendons in my ellbow from the triceps and biceps connections, before doing squats and benchpresses.
Doing so with cables and nearly no weight on it, just to stretch out the muscle and tendon without putting stress onto it.
I find this greatly reduces the times these tendons get inflammated. And a badly inflammated tendon isnt nearly as flexible and can tear quicker, while a bad inflammation is an injury on its own.
So are the patella tendon, quadriceps tendon, and all those near the innter tigh. I could squat without warming those up, but especially the quadriceps tendon tends to start hurting pretty badly when putting significany %max on my back for a bit of volume
You feel it stretches itself out under the weight, but you also feel its in danger of getting damaged cause its not flexible yet. Dynamic stretching works on that
I do static stretching aswel. But thats not for injury purposes, thats to lenghten the hamstrings and romboids for example, to get a better form in the excercise.
