Sté USAT&F, NCCP Run Coach on Instagram: "SPEED PHASE TRAINING Every aspect of your training should change from phase to phase! A disorder-broadened first-order transition occurs over a finite range of temperatures where the fraction of the low-temperature equilibrium phase grows from zero to one (100%) as the temperature is lowered. This continuous variation of the coexisting fractions with temperature raised interesting possibilities. On cooling, some liquids vitrify into a glass rather than transform to the equilibrium crystal phase. This happens if the cooling rate is faster than a critical cooling rat… Web1,993 Likes, 18 Comments - Sté USAT&F, NCCP Run Coach (@coachstedotcom) on Instagram: "SPEED PHASE TRAINING Every aspect of your training should change … chip it sherwin williams paint
