You adapt pretty quickly to however you want to setup your fast. The typical recommendation is to workout fasted at the end of your fast, so you can eat afterwards. Have something light to start, then your first full meal shortly afterwards.

I do heavy PPL lifting program 6 days a week and have been doing IF for 3 months. The first 2 weeks were mentally tough at the gym, but after that, the gym really helps me finish off the last couple of hours of my fast and I haven't noticed a negative change in energy levels or strength.
