I used to visit a recovery lab with a whole bunch of toys including an ice bath set to 54 degrees F, which makes sense with recommendations I’ve seen…generally not to go lower than 54F, and that the ideal time is somewhere between 5-10 minutes. Then I bought a $4 thermometer and found out the water in my bathtub at home usually comes out around 56f, so no reason to pay for some expensive facilities.
That recovery lab does have Normatec Recovery Boots, which seem to be like foam rolling on crack, for your entire legs minus the butt. If you have that “one muscle” that is very tight, a foam roller or lacrosse ball may be better, but if your legs just feel stiff overall or across large muscles(e.g. quads) it hits a large area pretty well. My experience with them has been excellent, but perhaps Scott has some more thorough information.
