Adjustable Weight Cast Iron Dumbbells Set 105lbs - Home Gym Equipment for Strength Training & Muscle Building - Perfect for Home Workouts, CrossFit, and Fitness Enthusiasts

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 amazon, 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.
