¹ One group of baseball hitters practiced by first facing a group of fast balls; then moved on to curve-balls; then moved on to knuckle balls.
The second group used Random Practice mixing up the different balls. The second group improved their hit rate in play by 57% on average;
while the first group only showed a 25% improvement on average. 

Let’s make sure that you’re getting the full benefit from the time you spend practicing. You’ll hit more good shots.
