Note: there are 2 trains of thought for Freestyle/Crawl stroke – conventional wisdom suggests that the arm should extend as far forward as possible on the recovery, entering fingertips first with the arm engaging the catch from the surface of the water. This method creates upward force instead of forward propulsion during the engagement of the catch and it adds a lot of undue strain on the shoulders. Newer wisdom as trained by www.swimmingtechnology.com trains a ‘push’ at the end of the stroke by bending the wrist backwards as it completes the full stroke, pushing water to the toes as long as possible. On the hand entry, www.swimmingtechnology.com trains that the hand should enter close the head and extend forward at about a 45 degree angle downward (where the eyes can SEE the hand as it enters and as it catches water). Their method trains to maximize the forward propulsive phase of the stroke while minimizing undue shoulder strain.
