Is this too much for one workout?

I'm starting a triathlon training program but would still like to lift weights once a week. My workout is not structured at all and I'm probably missing muscle groups, but this is what I'm doing. Any advice for exercises to add or remove would be appreciated.

As a disclaimer, this is not "AI" it is just me exporting my workout from an app.
