Well each injury ive had in the past few years may have been overuse or just freak happenings. few years ago plantar fas (activated while running on a garbage track), last year right calf tear (ill assume from the increased number of rope skips I was doing), this year low back while doin deads and other calf last week.
I actually try to keep track of volume and ive increased therapy. So it could be age saying I need to drop the volume even more. Maybe the 2 hi, 3 lo a week schedule.
