Training with the Atlas Trainer

Training with weighted rucksacks has its roots in military training.

Weighted Rucksacks are the Foundation of Training for Humping

Rucksacks are an important part of military training.

They are used in many different environments, including:

  • boot camps, where soldiers learn the basics of handling their equipment and training with other recruits
  • mountain warfare schools, where soldiers learn how to handle themselves in harsh terrain and climates
  • infantry schools, which teach infantry tactics and strategies

Get a Rucksack with a Good Solid Frame

When you are training with a rucksack, you will be carrying heavy loads.

A good rucksack frame that is designed to carry weight should have padding and support for your back and hips.

The padding can be foam or mesh, but it should be firm so that it does not give when you put weight on the bag.

Ideally, like the Atlas Trainer, it will also have a waist belt and shoulder straps that are adjustable for different body sizes.

It’s also helpful if there’s a hip belt as well as a sternum strap to keep the pack from shifting from side to side while you are moving around in it.

Get One that has a Padded Waist Belt

A padded waist belt is an essential feature in a rucksack. It helps to distribute the weight of the rucksack across your hips, rather than on your shoulders and back.

By doing so, it reduces stress on your back and makes a smaller difference to its performance than you might think.

The key thing is that the padded waist belt should be comfortable for you.

Train to Run with your Rucksack

Running with a rucksack is different to running without one, so it’s important to learn how to do it properly.

The benefits of training with your rucksack include building up strength, stamina and endurance. Running with a rucksack also helps build muscle tone in the upper body muscles (making them look more defined).

Humping Techniques

Train to do humping techniques over rough ground and through thick woodlands.

Humping techniques are used to move over rough ground and through thick woodlands. The high crawl, low crawl, and high walk are all humping techniques that can be used in these environments.

Humped movement is characterized by the use of many short steps with the lower limbs making contact with the ground at each step.

Humped technique is used to move over irregular undulating terrain such as hillsides and mountain slopes where there are deep gullies or ravines on either side of you.

It is also useful for moving through thick vegetation (e.g., undergrowth) or steep sideslopes of streams or rivers that make it difficult for you to get up onto them (or even just down into them).

Increase Weight Gradually

Don’t try to increase the weight of your ruck dramatically in short periods of time; this is a long-term process.

Training with rucksacks is a long-term process. It takes time to build up endurance and strength, so be patient. You will see results eventually, but you have to stick with it.

The Outdoorsmans Atlas Trainer is an excellent choice for helping you to achieve these goals.
