First time posting in this thread for me. I've been doing 5BX nearly everyday for the past two years, after not really being active unless hunting. I'm middle age, but am using the charts in 5BX for flying crew half my age. If I can do it, anyone can.

This spring I started going back to the gym. And this summer I started weighted pack training. I do some sort of physical activity six days per week and take one day off completely.

Yesterday I did kettlebell swing, one arm; kettlebell shoulder press; barbell bent row; goblet squat; simulated sled push on treadmill (new favorite); 30 minutes on stationary bike at low heart rate.

Today is supposed to be weighted pack day, but man I am sore from yesterday!
