A Pamela Fortner, NASM Elite Trainer , Fitness, answered. When foam rolling, you should stay on the tender spot for at least 30 seconds or until you feel less tension in that spot. It may take a few sessions with your roller before the adhesion is totally gone, but the tenderness should begin to go away.
There is no magic number when it comes to how long a pre-workout stretching routine should last. In general, however youâll be doing two to three static stretches as a part of your warm up. If you perform three stretches and hold for 20-30 seconds each, thatâll be about a minute and a half.t will depend on the muscles that you need to stretch, typically 5-10 minutes. You will want to foam roll your tight muscles and do some static/active stretching (5-30 seconds per muscle depending on whether you are doing a static or active stretch).
