How should athletes promote sponsors on social media without being too commercial?

Use organic, natural promotion by featuring sponsors' products while doing regular activities - like wearing sponsor hats while working in the shop or using sponsor products during car preparation. Tag sponsors and use their hashtags so they see the content and get notifications. You can also create intentional promotional content showing how you use products. The key is mixing organic mentions with planned promotional posts, keeping content personal and relatable rather than overly salesy with too many logos.
