I do this every year. I wear my pack as frequently as possible even if it’s 10 minutes a time. 20 minutes on lunch breaks, hit the hill with the pack on. Mowing the yard takes me an hour 15. Cleaning the pool. Walking the kids to the park. Exc. One year a while back I did very little pack training, drove 1040 miles hit the trail head with an improper fitted pack, figured i was 55-60lbs for 6 days and it was miserable, every year since I’ve vowed to put in the work where possible. It makes a difference towards the end result.
