I’m following the 24 week mountaineering plan and am in the final weeks where there is only one short max maintenance workout a week. In my max strength period I worked up to a 170# step-up for 5×5 and 150# lunges for 4×4 twice a week. For the past 5 weeks I’ve been doing 3 sets of 5 reps for step-ups and lunges at those same weights and they actually feel easier each week. I was skeptical about maintaining my strength with only one workout that lasts just 50 minutes including my warmup but have been happily surprised.
