The key is what is the ultimate meaning of your blessing message. Can I understand that you want to remind your customers that it is the weekend and it is time to go to the gym to exercise, just like what kind of blessing messages are sent by onesmser SMS platform?

If it is just a simple blessing message, you can edit it like this:

Busy, it's the weekend again. Li Xiao here warmly reminds: Persisting in long-term exercise is good for health and physical and mental health. Have a nice weekend and don't forget to exercise! Add your club name here.

This will help to improve your popularity.
