My experience with self foam rolling
I have 5 types of foam roller at home, 3 foam roller with different density and length, 1 foam rolling stick, 1 massage ball and 1 foot roller. I started foam rolling in 2016 after looking for ways to shorten recovery time and reduce muscle soreness. For the first few months i would usually spend about 30-45mins per session for whole body release. Nowadays i just foam roll a few minutes on target muscle or 20mins for the whole body. I find it there isn't much difference with the time spend on rolling, the effect of rolling 20times over your quads and 10times over is the same. I find the longer you spend the more likely you are going to make your muscle more sore and tired, i usually spend alot of time using massage ball to roll over my whole back and i always got the rolling marks/bruise at my back. I thought i should roll over and over again over the trigger point or point of tenderness until it gets better. But this is definitely not the case, no matter how much force or time ...
