I ALTERNATE I RUCK 3 DAYS ONE WEEK AND THEN RUCK 4 DAYS THE NEXT WEEK. I always RUCK in the mourning.  I walk 6 days days in the evening for 2.1 miles and walk 3.2 miles the mourning.  
My rucking backpack weight is 23lbs . I am adding 4lbs every 2 weeks.

My distances for Rucking and walking are the same.  My average walking speed is 3.5 to 3.9 mph I getting  11,400 total, and Sunday is my rest day . Walking,  Rucking and wind sprints.  Are the 3 best cardio exercises that you can do .

Good content Dan. I ruck 3-4 times a week with 20-30 pounds usually 5-6 miles. Do it for general fitness and helps me maintain my weight

👍

Just getting into rucking. First one was this morning. Looking forward to it becoming a lifestyle

I ruck four times per week for 25-35km each (12-25% BW) with 200-500m of elevation and suitcase carry a kettlebell (40% BW) for 8km each twice a week with 100m of elevation.
I also do lift, but not as much as i used to. Sadly, i'm also 44 and can't recover fast enough to do more :'D
This friday i go for a 50km session with 18% BW load...the distance will of course depend on how i feel.
I started rucking 4 years ago and lifting 20 years ago.

The real question is when shouldn’t you be rucking?

Dan, i just received the feather ruck bag and boy i am very impressed after dialing in the support, i already feel the load off my shoulder and neck..which i was suffering with another ruck bag i had..cant wait to start!

I like your plan for lifters to ruck 2-3x a week.  I have a 6 day strength training routine: Push Day 1 and 4, Pull Day 2 and 5, and Lower Body Day 3 and 6.  Currently I do one ruck on the weekends, roughly 3-5 miles with about 45 pounds.  Where would you suggest I put another 1-2 rucks, and how much weight?  Thanks!
