Hello RallyPoint, hope you are all doing well. As I am soon to enlist as an infantryman, I have been practicing rucking for the past month (sadly, I haven't been able to go past even 3 miles without caving). I have a vet friend of mine (former 0311 marine himself) that has insisted (for the life of him) that the only way to ruck is to keep it bottom heavy (have all the weight at the bottom). Although I have no doubt he knows of what he speaks, I can't help but question if there is a better way (at least one that has escaped him during his time in the Corps) to ruck. I keep hearing from many others of doing it the complete opposite (top heavy) instead. Not gonna lie, having it bottom heavy tends to sag my ruck (a USMC issued ruck that I bought from a surplus store). It sags to a point where it bounces a bit and it also drags my ruck back down almost in a way which pulls me back. Am I doing something wrong here? Hope you guys are all doing well.

P.S. Up top is a pic of the ruck I bought from the surplus store.

Marines hump heavy all the time, no way around it for Infantry. Especially the 21 and 31’s. Your hips are where all the weight bearing happens. The Marine Mountain Ruck is designed to work like that. The MOLLE ruck, not so much. It really depends on the ruck style. I have a MOLLE that I packed high. Did runs with 45 pounds in it. Same with an ALICE. My Mountain ruck I packed low. My Mystery Ranch bag I packed mid-weight. It depends on the style of bag and your comfort level.

Another thing to take into consideration is that if you haven’t rucked before is to take baby steps unless you like stress fractures and femoral head injuries. Wear soft shoes and build up to distance and weight.

We marched OSUT Trainees around the running track in soft shoes with the prescribed packing list up to the 6 mile benchmark as a risk mitigation measure because those musculoskeletal injuries were becoming so common.

Just posted a pic of the ruck, if you could look at it tell me which one it is? Thanks for the input, Sergeant.

That’s the Mountain Ruck it should have pouches on either side of the exterior that will stretch to about 8 inches in diameter. It has straps galore too. There should also be a partition that is either zip or 550 cord secured depending on whether it’s an early or late production model. The frame should also only be 2 aluminum bars that slide into pockets. You can adjust that ruck to run high and tight, which is how the Army teaches is the best way, but you will need to use the partition and strap everything down really well. The waist belt on the ruck you have should also be massive in size compared to the other rucks you have looked at.

Also, if I were you I would stop rucking until you get to INFANTRY OSUT itself, they are going to teach you how to do it and 22 weeks is more than enough time for them to ease you into it and they will ease you into it from point zero (not being able to ruck a mile). Reason your failing can be many, not enough rest, not eating balanced meals, jumping right into a fully weighted ruck and expecting a miracle to happen, etc. If you were going to RANGER or SPECIAL FORCES school, different story but Infantry OSUT.........rucking prior to the course is unnecessary and you could injure your back if your not careful. Also they give you rest periods during the ruck.....which you are probably not taking on your own. Want to prep for Infantry OSUT don't attempt the military things or heavy weight loads. do things like ride your bike for distance to build your legs up. Or do some deep knee bends using just your body weight. Do Cardio. You don't need to show up like Rambo or the Terminator. The course is designed to build an average person off the street, into a Infantryman. RANGER OR SPECIAL FORCES, different story and those courses expect you to be in good condition.

If I should decide to go to RASP, would it be recommended then?

Jake Lang - Not on your own, consult with a current or recent RANGER. The reason I say this is about 10+ years ago I used to be a Moderator for the Army Forums on Military dot com. It was like once a month had a future soldier write in they screwed up their lower back or some other muscle trying to get ready for BCT with no supervision on what they were doing. One guy was running around with a ruck with barbell weights in the bottom (bad). Also what they say about micro fractures in bones is correct. If your used to a sedentary lifestyle and just jump into something like this it can cause larger medical issues. The Drill instructors have trained newbies across several cycles and are experts at training people up to be good runners, road marchers, etc. For RANGER or SOCOM find someone recent, two websites here not sure if they are still in business. Professional Soldiers dot com for SPECIAL FORCES and ArmyRanger dot com for Rangers. Some of the vets like to abuse so present yourself well because there are others on those websites that know folks that will be your training cadre more than likely and you don't want them to say "hey watch for a recruit so and so". Social Media is bad that way. Also, with added exercise you should be taking a basic multi-vitamin in the morning to help ensure your body is not falling short of anything.

The goarmy.com ranger page literally has a workout plan. I personally did a lot of weight lifting for legs and slow distance running. Never had any real issues through 19D OSUT and the rucking standards were the same. It was also good for me mentally to know that I could run this distance, or close to it non stop. So with a ruck on walking and talking breaks to fill water it didn’t seem as bad as it for others. Although that Georgia humidity will make you sweat.

Outstanding advice, they’ll teach you the best way to do it because any platoon or squad is only as fast as the slowest man... when it counts. In training you may or may not be on your own at times looking for times on courses. The type of pack counts too, my experiences were very minimal, but with ALICE packs the lower the pack the worse it was. It was easier to get it up to about your shoulder blades for better balance, they were basically lousy packs to begin with imo and always wanted to slide down.

You never want to pack your ruck so low that it feels like you’re dragging a big anchor and you never want it so high that it pulls you when you lean left or right. Depending on what ruck you wear and how you like to ruck it should be as close to your back and between your hips and shoulders as much as possible. Hips if you use the hip belt, shoulders if you don’t. Your weight should never be on/below your butt or over your head if you can help it.

In the Army you have two kinds of rucking - fast and light, or slow and heavy. Your timed rucks will be light, 35 pounds before adding water and 12 miles in three hours at a 4 mph pace. It’s just a little faster than comfortable on a road, and a bit difficult in the sand. Your heavy rucks will usually be 55-70 pounds before adding food and water. You’re usually moving at 1-3 mph, usually over rough terrain, and usually for several hours at a time. Every selection in the Army is based on rucking. SFAS is rucking for weeks. Ranger School is rucking off and on for two months.

You should not be increasing your weight or distance any more than 10% a week and at your level I recommend it’s no more than 10% every two to three weeks. Rucking isn’t about muscle it’s about tendon and ligament strength and they take approximately five times as long to strengthen as your muscles.

Jake Lang If you are humping 100+ pounds of gear 3 miles in an hour, you are doing better than most Soldiers, already. To include your standard infantryman. That is not me telling you to forget about trying to improve yourself, just letting you know where you stand so you give yourself the freedom to pace yourself to avoid injury.
At this point, my recommendation would be to drop literally half of the weight, work with 50 lbs., and work on your endurance. Don't worry about your speed, just work on getting to wear you can walk with the weight for 4, 6, 8, 12, or even 25 miles. This will NOT happen over night or even over a month. But trust me, once you get to thw point where you can hump 50 lbs. for 12 miles, even at a slower pace you will be able to FLY when you only have to do 4.

SFC Casey O'Mally - Sergeant, I highly doubt I'm doing better than most soldiers. When rucking 100 lbs. in 3 miles at 1 hour and 3 minutes, I am near dying. Although I am not gassed out completely like I do with my runs (perhaps my biggest weakness), I can't help but make that stop on the 3rd mile to return home, huffing and puffing while my shoulders and backs are sore as hell.

I tried 50 lbs. once at 3 miles (with a 47 minute score), it was a challenge, but I still had that "I can keep rucking" mentality at the end. I guess I could try 50 lbs. for 6 miles now and work my way up to 12. I guess once I get that 12 miles down, then it would be to make it down to less than 3 hours. Any more words of wisdom, Sergeant?

Thanks ahead of time for the tips.

Jake Lang So there are two ruck “standards” in the Army. The first is rucking with a 35lb ruck (before you add water) a distance of 12 miles in 3 hours or less (4 mph or 6.5 kph, the Army uses the metric system when measuring so get used to the conversions). This is the standard for literally every Army school or selection (RASP, SFAS, Ranger, Air Assault, etc.) However, when conducting tactical foot marches, the Army adheres to ATP 3-21.18 Foot Marches. The standard per ATP 3-21.18 is 4 kph (2.5 mph) with a 40lb load, decreasing for every 10lb over 40. So with a 100lb (ruck and body armor) load on easy terrain, with no enemy contact (e.g. on a road) the rate of march decreases to 2 kph (1.25 mph) with a 15 minute rest break after the first 45 minutes and a 10 minute rest break every 50 minutes thereafter. The reasoning behind this is that at the end of the march, the formation (squad/platoon/company) still has to be able to conduct what ever mission they have been assigned. We just conducted a 15.5 km (10 mile) tactical march and allotted 6 hours to complete because they had to hit an objective at the end and couldn’t be smoked by the time they completed the movement.

Bottom line, decrease the load you are training with, you don’t want to be pushing yourself too hard because you think you aren’t meeting some standard than you’ve set for yourself, without knowing what the actual standards are. The NCOs and Officers that are giving you feedback are telling you these things for a reason. Probably the vast majority of us tried to go hard all the time when we were younger and now we’re paying for it (I’m 31 and ask me how my back feels after Ranger school and my time as a Scout PL in a light infantry battalion). Heed their advice, learn from our experiences and know that we’re telling you this because we’ve lived it.

You’ll find once you get to OSUT that you’re well ahead of many of your peers and remember, the whole point of OSUT is to take civilians and make them into infantry soldiers by the time they graduate. Will you be Billy Badass at graduation? Hell no, but you’ll have a good solid foundation on which to build.
