I ordered a bunch of strength training equipment from Urban Strength. I love that they specialize in bodyweight training for things like gymnastics and ninja warrior training, which is fast becoming big in Australia.

The Urban Strength gymnastic grips are leather that have molded nicely to my hands after a couple of training sessions. The gymnastic rings have a strap length that gives you plenty of clearance to a roof or tree branch, the straps are easy to fasten, the grips are standard Olympic thickness for hand sizes, and I fully trust their durability hanging upside down on them. Also got some of the chalk blocks and resistance bands, which are staples for anyone into calisthenics.
