Light Exercises for After an Operation

I’m having some oral surgery soon, and for 1-2 weeks I can’t do any serious physical activity. Taking a week off won’t cause muscle loss, will it? I’ll make sure to take plenty of BCAAs and get enough calories. I’ve been lifting for 8 months straight, and for the last month I’ve been doing a 5x5 program.

So I’m thinking lots of pushups and dips. Maybe bodyweight squats. I want to wait at least a week before I touch the weights. Any other ideas?
