One of my good friends (F45) who I (F30) know from the gym is struggling financially. She's a great mom, but due to her daughter's medical problems​ and her husband being laid off from work she's fallen on hard times. ​Because working out is the one thing stopping her from losing her sanity, she asked the owner of the gym for a discount on her subscription costs in exchange for her doing some cleaning or otherwise helping out.

Because the situation with her daughter takes up so much of her energy, I'm worried this extra 'job' will cost her too much. I would like to propose to the gym owner that I'll cover 50-75% of her subscription for the next 6 months, but that we keep it between me and him. He can then just tell her he'll give her a 50-75% discount in exchange for her covering maybe one class (just so she doesn't feel like charity). It would save her about $500-600.

Is this a good idea? Is there anything I haven't thought of? I'm in a position where I won't miss the $500 and I would never tell her so it doesn't affect our relationship. ​The only thing that worries me is if she would find out and feel.. I don't know? Offended? Please let me know if there's anything I haven't considered.

EDIT: Have decided against it seeing as it might cross a boundary. I am open to hearing suggestions as to how I could offer to pay the subscription or whether I should just leave it alone.
