I just started the rr on the 1st of the year, and I've been loving it. I bought these two weeks ago: https://www.amazon.com/gp/product/B01GKKJ8SI/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
I picked them because they have the clips for easy adjusting. I LOVE THEM! Also, I have noticed an immediate impact on my training because I'm using them.
I'm not strong enough to do more than a support hold and some push-ups, but damn, those got hard quick!
Get them, you'll be happy.
