This is something I’ve been trying to figure out since I became a firefighter 5 years ago. We work a 24/72 schedule. The best thing I’ve come up with is making an 8 day training week- 2 work days and 6 days of training. Having that extra day in the week really helps with getting all the training in. Especially if I need to break up a session, or need another rest day coming off shift, recovery scores/ HRV are shot. Lots of flexibility.
