Hi quality and very versatile resistance bands
I have found the new U. S. Elite Resistance Bands set to be the finest workout tool in over 60 years of training. The variety of exercises that can be done is almost immeasurable. The ones advocated by James Grage are effective and science based. There are many more and the only limit is one's imagination. The bands are especially effective for me because of joint injuries. I cannot do regular squats or bench presses with barbells due to shoulder and hip injuries. The bands allow me to do safe exercises that are substitutes for weights and, in some ways, actually more effective.
