This trainer is a wonderful product! It's an extremely versatile training tool allowing you to add weight and get in sheep shape. It so nice to not deal with sand bags or weight balls inside your pack.

I recently purchased another one since "donating one" at a local gym, after I left it behind after a solid training session.
I purchased the Black this time and love it, not just because of the black color, but a few things I noticed since my last version about 3 years ago. The hit belt seems a lot more comfortable and i love the loop on the straps, to help keep things adjust with ease.
This is my "go to" Ruck Trainer, aside form local hikes, i use this for box step ups, air squats, lunges, you name it.
I love walking in to the gym with this and people wondering what the heck it is.
if you are a hunter, this is a must have training tool, whether in the gym, at home or on a trail, this is a MUST HAVE!.

I’m 68 and the mountains get higher and steeper each year. For years have trained using squats and elliptical. Certainly helpful. The Atlas is much more task specific and it’s also much more fun to be hiking instead of in the gym all the time. The trainer is well built and lives up to expectations in every way.
Just a note on positioning. Make sure the waist belt is above your hips otherwise seems to put pressure on the glutes causing a feeling of deep muscle fatigue from either vascular or neurological pressure. Once I figured that out it was off to the races.
Absolutely love this training aid

I managed to break in my trainer this morning with a 7 mile, 65# ruck march. It was one of the most pleasant (relatively speaking) rucks I have done in a long time. The Atlas Trainer sits nicely, spreading the weight out across the hips and shoulders. I didn't need to make numerous adjustments to the straps or shift the weight around as I have done when using regular ALICE packs or other assault packs. My only complaint; the shoulder straps sit right on top of the bolt in the head of my humerus, which wasn't comfortable. I was able to mitigate the pain slightly by tightening the sternum strap a bit. I needed it tighten it all the way for full relief. Despite the great cleavage it gave me when tightened all the way up, it restricted my breathing a bit, so I had to keep it a little too lose. That is in no way the fault of the pack's design. I no longer meet manufacturer's specs since I have non-OEM parts, so I can't expect some products to work as well as they will for others. An option for contoured shoulder straps might be nice.

TLDR; If you need to walk far with heavy stuff on your back, get this trainer. You won't regret it.

Just received my Atlas Trainer and felt like a kid again ripping that box open!

Training on the morrow for the next 4 weeks for the big hike.

Thanks guys!
