## Description

This set consists of a pair of brand new 105lbs (52.5 lbs x 2 pc) adjustable dumbbells (5 lbs x 16pc, 2.5 lbs x 4pc, 1.25 lbs x 4pc, handle x 2pc, collar x 2pc). Not everyone who is interested in getting a better body through strength training has the necessary room in their home for a dozen or more sets of dumbbells. This adjustable and versatile dumbbell kit is small, convenient, and easy to store. You will be able to perform the widest variety of exercises by working out with varying weights. The kit is simply the best and a must have!

Review: You can fix your shoulders, too! (if you've a slight build) - What a great set! Beautifully finished, the spin on the nuts is flawless. Besides the obvious strength-building, I learned such a cool exercise from Dr John Bergman (on youtube) that is fixing my recurring shoulder pain from a rotator cuff tear and surgery about 10 years ago. You should hold just enough weight to pull your affected shoulder back down (if your problem is weak/fragile supraspinatus, like mine), in both hands with your thumbs forward (rotating that cuff into neutral), then just very gently swing your arms at your sides just a little bit. Your goal is to go no further forward nor backward than the depth of your thighs. This pumps the tissues around the supraspinatus, the muscle that stretches from the top of the back face of your shoulder blade (right next to the spine), under the hard edge of the scapula (you can feel when your reach over your shoulder) to connect to the tip of your upper arm bone. This is healing in a mechanical way, increasing the fluid that surrounds the tendons and fills the shoulder joint. He calls it a "super filtrate of blood." The ONLY way that filtration happens is through movement. When we limit our movements to what is required most of the time our tendons literally dry out. Then they become inflamed and we are off to the races. I find that the rods alone are heavy enough to do the job. I stand with my shoulders back and ears over them, hold the rods in line with my arms, so they act like 6th fingers as I gently swing my arms subtly. You have to go slowly, giving time for the alternating pressure to squeeze molecules of plasma between the collagen fibers, which are tightly packed in a tendon sheath. You will learn all about the muscles that stabilize your stance, too, as you challenge them to hold you still against this strangely oscillating force. You want to remain aware throughout the exercise that the object is not to increase intensity in any way. I find myself giving in, sometimes, to the rhythm and exceeding the parameters. You just want to accomplish the pumping action. Not to say, after, it's not wonderful to throw an appropriate amount of weights on and enjoy them in the conventional way! (For the shoulder fix Dr John recommends kettle bells, easy to hold in the neutral position, 5 lb or so, whatever passively returns the shoulder to neutral for women and up to 20 lb for men. I'm sure those are available here on desertcart, too!) At 2.5 lb, the rods alone are fine for me. It has greatly reduced my pain, both working and sleeping. And I'm starting to really feel strong in my frame, again.
Review: Pros/Cons - They are solid dumbbells. My second pair. Not really worth this price, but you can't find anything better priced due to pandemic supply and demand. I bought an identical pair in 2016 and paid $100 for the set plus shipping. Pros: Will last forever if taken care of. Somewhat cheaper than modern quick adjustable dumbbells. Quick free shipping. Cons: Anything but convenient to adjust weights. Black rustproof enamel was all flaking off upon arrival, making a mess with use and not protecting anything. The threaded plate guards come slightly undone each set, so double check each time. Regarding seller: They arrived in separate boxes, days apart, which was a little concerning. When contacting the seller, I never heard back.

### ⭐⭐⭐⭐ Very nice but not perfect weights - a lot of functionality for very little $
*by N***S on February 6, 2016*

PROS: Dumbells shipped very quickly Rubber gaskets help keep everything tight and quiet For the money, the amount of weight is unbeatable If you need more weight, you can buy four ten pound plates and go from 52.5 to 72.5 pounds a side. With a good bench you can get a pretty complete workout - I got it to supplement my barbell setup Crude finish but I don't anticipate it will be an issue Came with extra rubber rings for some reason CONS: Chrome plating not that great, splinter went in my hand. Not a big deal and I don't expect any further issues Not going to win any awards for nice machining or smooth casting. Not quite as nice to handle as dedicated dumbells; you can't support them on your knees on their ends due to the bar sticking out. On the whole, totally satisfied. Wouldn't spend more for another product. Plenty of weight for me and fast shipping give this a solid 4 stars. Slightly nicer finish would get it up to 5.
