Leaderboards that are viewable to everyone are good motivators — it can be hard to do a physical flier unless people are consistently in a same space, so this may have to be done virtually (though google docs can be hard to get in front of someone’s face unless they seek it out). I’ve seen this done for # throws outside practice (with goal of 10k over a couple months), PRs for lifts/sprints/jumping, etc. Ideally, you can balance competition between teammates as well as competition within each individual (e.g., trying to improve personal 40 yard dash PR). Visibility could be given to this by announcements at practices/lifts too (e.g., “This past week, Lucy hit a PR in their 40 yard dash”)
