The Peak-End Rule
I always like to end my training with a good throw. I used to think of this tendancy as a superstition, but recently I have begun to think that it may actually have a real positive affect on my training, both psychological and perhaps also physical.
I’ve had this habit since I started playing other sports as a kid. In basketball, for instance, I inherited my father’s insistence of not leaving the court until I made my last shot. That’s a habit I continue today in pick-up games with friends and have carried into hammer throwing. This habit served a few purposes: it encouraged me to focus on technique if I wanted to ever leave the court and it also left me leaving with a more positive reflection on the game or practice. The same can be said with hammer throwing.
In April I read the New York Times bestseller Thinking Fast and Slow, by the Nobel Prize winner Daniel Kahneman. Kahneman is a psychologist whose research has focused on topics like the psychology of judgment and decision-making. In particular, he has identified many biases and heuristics that impact the way we think. One such heuristic is the Peak-End Rule. The rule states that how we judge experiences is largely based on how they were at their peak and at their end. For example, how we judge a practice will be affected by how far our furthest throw was and how well it ended. Numerous studies have shown this heuristic affects and will cause people to rate more painful incidents better than less painful ones.

After training with 
The first day of training in the snow each year fills me with the excitement of a schoolboy arriving to the first day of class. The snow mutes the air, leave a still, peaceful and relaxing silence to train in. I am not alone either. I was excited to see some of my young throwers not only train without complaint in the snow this year, but hit a few personal bests and brag about training in the snow on Facebook. It is a merit badge in winter throwing.
Experience is one of the most underrated traits for hammer throwers. You mostly need it when training is going poorly, and at some point that happens for every thrower. My season started off terribly in May and June with marks consistently around just 61 and 62 meters. It was frustrating to hear the officials read off marks that I could have easily achieved six or seven years ago. A few small speed bumps in training set my training down the wrong path and I had to scramble to save the season.
The best set of eyes I get to watch me belong to my training partner Dejan, a masters thrower who returned to the sport two years ago after two decades away. One thing we share in common is that our enthusiasm sometimes make it hard for us to boil down what we see into just a few words. But unlike me, Dejan sometimes produces these little pearls of wisdom that get to the point so well that I leave practice with a smile on my face as if I have found true enlightenment. After talking about visualization earlier this month, he threw this line at me: “Sometimes you have the right picture, but the wrong light.”
One of the most difficult aspects of training alone is focusing. I no longer have a coach there that will yell at me after every throw and tell me that I need to push the hammer more. After a long day at the office, it is easy for my mind to wander about my latest work project, what I need to pick up at the grocery store after practice, or even what my next blog post will be about. If I don’t watch out practice will be over before I know it and I will have taken all my throws without really thinking about what I wanted to improve.
