5:00 woohoo, i didn't see that coming. Such a good idea. Thank you.

[@markhowarth5294]

Make these and sell them. I’ll buy some right now 👍

Matt the inventor strikes again!

[@RedDeltaProject]

I prefer the title Super Caffeinated Mad Genius (it's on my business card) But sure, inventor works too 😂

[@winsonyyin6659]

Hope that RDP can have its own suspension straps, and I will definitely buy it!

Hey you Matt. Missed this as I was on a long flight but I'm very happy to see it. I remember you telling me that you were working on an updated version of the s trainer last month...HO BOY, I had no idea how far you'd surpass yourself! Congratulations and job very well done!

[@RedDeltaProject]

Glad you got a chance to check these out. it's been in the works for a while and there's still a few kinks to iron out but this is the basic design for now. Stay tuned for how to make and set up videos plus simple workouts using these as well.

[@oscarstenberg2745]

Seems great. I've tried making some of your earlier ones. Really great idea for travelling, fits in pocket and even though you usually can find some place to hang, these make it more consistent since the grip is always similar. I really love that you can use this version to do rows with the door. That's genius!

[@RedDeltaProject]

They work really well on the door, check out the latest video for a 10-minute door anchored back and biceps workout: kzbin.info/www/bejne/mZCzk2qBeKiLqJI

[@scottholmesptdptcertmdt2853]

Great job Matt! I have been using cam straps personally with handles from resistance bands for a while now. This could be a great video for some of my physical therapy patients.

[@RedDeltaProject]

Good idea, I've noticed the handles on bands are getting a lot better than the primitive variations I had when I was younger. way to innovate with what you've got!

[@harvestblades]

Pretty much what I made but used PVC as you did w/ the Bowline for handles & chamfered & sanded the edges as well as wrapped with hockey tape. I also included a prusik loop for and adjustable foot loop using some paranoid or even better some 5mm climbing rope. Great info here & what I recommend if you want to give suspension training a shot or don't feel like dropping $125-200 on a TRX!

[@IntoTheOutside000]

I underestimated how much more unstable these are than rings for pressing movements since you have no support against your arms/shoulders from the rings and straps. Not only do they easily rotate but slide parallel to the strap demanding intense rigidity of the wrist and grip that the rings do not relatively speaking. This can make it flat out dangerous for beginners as if the rings were not already. But after using rings for over ten years I can say I'm loving the challenge. I'm using 2inch thick aluminum handles for gorilla grip on the pulling movements making the grip the limiting factor on purpose for fore arm and grip strength gains.

[@DarkAloneMan]

Cool ! Well now i guess i have to improve my crafting skills

[@SlackerWannaB]

Genius!

[@BlessedTen]

This is perfect. Now I can balance all the push ups I've done with rows at the hotel.

Pretty cool Matt. Grinder reminds me of Mr Garrison's puppet lol

[@RedDeltaProject]

LOL, you're right he does!

[@chrisp7442]

Very nice, sir! Add some neoprene handle wraps to that foot sling and you can avoid having any digging/chafing from the straps as well. Adds some bulk, granted, but it's velcro, so you can detach when desired 🍻

[@RedDeltaProject]

Good idea. The 3/4 wide webbing is a little pressure on the bare foot so that's a good idea. I find it's just fine if you're wearing shoes though.

[@michaelkulman7095]

So, if a person made one is this your final take on them? Does this involve any sewing, do you just buy raw strap and raw buckles or do you use premade lashing straps? Do you have sources for materials?

[@sajlee]

Thank you so much for this video Matt. I made some of these today and they're brilliant! One question, how did you get all that webbing neatly packed into the handles (as on the thumbnail)? Many thanks for your content. Much love from the UK

[@RedDeltaProject]

I fold each strap in half 3-4 times and then stuffing the strap in the handle which covers about half way and you can fold the remaining strap on the handle.

[@sajlee]

Thank you

[@lukszakes2132]

I'd honestly consider buying those if priced appropriately and I'm sure I'm not the only one :)

[@RedDeltaProject]

Thank you for the support and feedback Luk, looking into a way to potentially produce these.

[@janmuller5721]

Haha how gregor moves xD

[@viveviveka2651]

Great design. Thank you. I'm thinking of trying it both with handles and with rings, but I'm not sure the rings will have any real advantages over handles, and will be worth it. Do they have advantages over handles?

[@RedDeltaProject]

Not a whole lot, it mostly just comes down to personal preference. Although, it's easier to do false grip stuff on rings, if you are into doing things that us a false grip.

[@viveviveka2651]

@@RedDeltaProject Thank you for that.

[@fj8350]

I really like the handles you used there. Where can i get a set?

[@RedDeltaProject]

I'll have to check and see if they are still available, but you can find something similar in fitness equipment retail stores if you have any in your area. I'll be making a more detailed video on the make up and set up for these later on

[@dellapoole2024]

@@RedDeltaProject Yes, I've been scouring the web for some knurled plastic handles and can't find any. All I can find is foam or rubber handles

[@fj8350]

@@RedDeltaProject I just made a set and they are AWESOME. I would suggest 1 inch pvc and 1 inch webbing (flat rope) for people with bigger hands and those who are used to using olympic bars. Other thank that the 3/4 in will work just fine, I'm sure.

[@idyllicandroid]

I have a pair of junglegym xt's (my favorite trx style straps) and Olympic rings with straps. Of both of these neither one is as easy to set up or compact as this! My Olympic rings have TONS of slack length that hangs about, but can be hooked over trees etc, while the junglegyms are neater, but you need to access what your hanging them from directly. GRIND STRAPS ARE THE BEST OF BOTH WORLDS, not even considering the locking foot loop engineering. This is genius Matt please reach out to investors or give me the okay to reach out for you. You deserve this

[@RedDeltaProject]

By all means put out some feelers if you have the connections I would love to set up some sort of production and distribution channels with these puppies, plus figure out how to make a more refined design if possible.

[@allancoffee]

@@RedDeltaProject I dont think your fans wants a refined product later, they want the rough stuff ASAP! 💪👀

[@tonyd6096]

Matt, what kind of cam buckle did you use. Was it a no sew buckle or did you have to get the buckles sewn on?

[@RedDeltaProject]

It's a sew on design but it came on the straps which are stock from strapworks.com

[@mikebarone2]

Love the simplicity. Have not bought my TRX or Monkii Bar 2 as of yet although $200 for the MB 2 is a bit much. My question on the DIY straps...I would believe the incorporated (colored) lines on the straps you see on TRX or some others is a valuable indicator when making adjustments. I could see myself spending more time attempting to adjust the level than working out. Although the ease of adjustment clip on the Monkii B 2 seemed very smooth. Thoughts to anyone out there that has purchased a cheaper set and regretted it?

[@RedDeltaProject]

You're right a graduated strap is certainly the way to go which is why I've ordered a prototype set with just such markings so keep an eye out for such a design in the near future.

[@mikebarone2]

RedDeltaProject...Thanks Matt! I appreciate the feedback. I’ll hold off buying anything for now. Another question/comment...I see that TRX and a few others have a single point of contact at the attachment to the top vs. the ones I see you use that can be spread out to the left and to the right. I assume that’s a critical feature. Thanks again....keep up the great work. 53 and it feels good to give up the travel to the gym and get back to old school finger tip push ups, pull ups, etc...like the old wrestling days. I’m pissed I had already purchased a bench for free weights that I probably won’t buy now that I found your channel. I would have purchased your contraption. 🇺🇸💪🏻

[@yawriats7]

Hey Matt? I've got something similar but the 1' straps are a bit too wide for storage. Where did you find those 3/4' ones? I've searched everywhere. Also would 30' ones be Overkill?

[@RedDeltaProject]

I get my straps from Strapworks.com and you can order all sorts of widths and lengths.

[@moawada]

Amazing, how did you do the foot strap?

[@RedDeltaProject]

Pretty simple, just loop the strap back through a second time after you run it through the handle. I'll be making a few set up and workout videos later this week to demonstrate

[@moawada]

RedDeltaProject i will be waiting for those videos, all the best Matt 💪🏼

[@chrisrose323]

[@chrisrose323]

@@RedDeltaProject Here's the thing though. I would be ok if they didn't send me the wrong ones. On the order page the handles was the solid hard rubber kind. The ones I got was those soft squeezy ones.

Is this version 4.5? I think I'm using your version 3 or so. 😀

[@RedDeltaProject]

At this point, I've long lost count. Although, this is probably version 4 of the strap system I started about 10 years ago.

Ok, so I just put handles instead of rings ón the straps?

[@oscarstenberg2745]

You missed the part that allow to use it with doors
