Socom:
According to allot of the reading you can find from the fitness training
books
on CCT/PJ, already posted forums, and even you-tube; the front
crawl is what teachers use to refer to the arm motion. The
freestyle is the use of the front
crawl + the flutter kick. There are veracious to the
freestyle as well. Like for long distance swimming I prefer using the front
crawl arm stroke with a whip kick; it saves a lot of energy from the legs while still propelling you forward.
To answer the second question, straight from the “the united states air force elite
workout”
book
… “fin swimming is: “ keeping one arm locked out in front of the body to guide the body in the intended direction. The other arm trails behind or also propels in a sidestroke.” I would suggest to pick up all the material (
books
) you can that already exist; most of the questions asked within these forums have been answered for at a price of about 15 dollars.
