I have used reward token in my coaching and still using it to date. I am currently attached with the junior performance program of my state’s tenpin bowling team. Our athletes train 6 times a week with only Fridays off.
Every month we have roll-off between trainees and those that finish on podium will win themselves a signed national jersey by our country’s elite bowlers. There are 12 elite bowlers in our national team and our training program is 10 months. It becomes a sudden motivation for the kids to try and do well in the roll-offs and collect all the various shirts. One of the curtain closer for our program, is the Milo Junior International All-Stars at the end of the year. I would then arrange for the national athlete to have a “selfie” session with the kid/s who have won their jersey.
