LiftLeaders website idea

Hello fellow software developers and entrepreneurs,

I have an idea for a new website called LiftLeaders that is dedicated to compound lifts. The website would allow users to upload videos of their 1 rep maxes, share them with the community, and track their progress. Users will be placed in different tiers based on their strength level, which will be determined by their 1 rep max. Each tier will have different rewards, such as digital collectibles, and access to certain features.

I would love to get your feedback on this idea from a technical and business standpoint.

Are there any technical challenges that come to mind when building this kind of website?
How would you set up the weight tiering system and digital collectibles rewards?
What kind of monetization models would you consider for this kind of website?
Are there any similar websites or platforms that you know of?
I appreciate any feedback you can provide, and I look forward to hearing your thoughts.

I have a regular 9-5 dev job. Let me know if you would like to get in touch to help build the frontend and api's

Thanks,
