I static stretch and foam roll most of my body most days. If I'm busy I just do the problem spots. I do dynamic mobility stuff as warm up. If you have one particular problem spot I'd stretch it several times a day, dynamic and static, and try to figure out if something is causing it- how you sit at a computer is to blame for most people's problems.
Mondays: Run with club Tuesdays: Yoga in the afternoon and might run with triathlon Wednesdays: Run twice with club Thursdays: Swim Fridays: Rest day! Saturday: Race or long ride Sunday: Long run, spin, gym, swim
I don't do all of these each week but basically this.
I though you only used it for your back? What's the purpose of foam rolling and is it working for you?
I roll the vast majority of my body. I'm one of those people who takes their own foam roller (and rolling ball) to the gym.
For my back, no not so much, it's well beyond too ****ed for foam rolling but sometimes when it's annoyed it tightens so rolling it can help make it more comfortable.
Generally, it's like getting massage, helps recovery, reduce tightness, dealing with 'knots'/trigger points etc.
