These are some of my favorite disc golf instructional videos for backhand throwing. The backhand is the most basic throw in disc golf. Some people find a forehand to be more natural for them. It’s not for me.
Kristian Kuoksa, a 1000+ rated Finnish professional disc golfer, says to come up through the legs to generate more power as you release the disc. Most importantly, for me, he also talks about keeping the elbow up and out, which helps keep the hand outside the disc, generating more spin. I tend to start with my elbow out and then bring it down and in during my pre-release forward motion.
