Hi @BrodyE, welcome to the Community! 
I had a look at the available triggers and actions for the TrueCoach app and I’m not seeing a “New workout plan” trigger or a “Complete Workout” action. I’d suggest contacting our Support team here to submit a new feature request for those to be added. That will flag to need for that sort of functionality to the developers of the TrueCoach app.
Usually in this sort of situation Webhooks by Zapier can be used to connect to the app but it requires a the app’s API to be public. And I couldn’t find any public API documentation for TrueCoach online, so it looks like that approach might not be possible at the moment. Would be worth reaching out to TrueCoach directly though, to see if they’re able to provide you with access to their API and documentation, just in case they can. 
Keep us posted on how you get on!
Hi
@SamB Thanks for your reply. I had come to the same concultion but want to double check taht I wasnt missig anything. I will reach out to TrueCoach and Zappier Support team
Thanks soo much.

You are most welcome, @BrodyE!
Thanks for doing that, and sorry for the delay in my reply here.
Look forward to hearing how you get on with TrueCoach - hopefully they’ll be able to provide you with access to their API to get things sorted via Webhooks
