I've never flipped a tyre of any significant weight so super sharp technique has not been necessary but by coincidence I was reading an article yesterday that emphasised not adopting a sumo style with arms inside the knees to avoid bicep tears.
What interested me was the following:
When using a tyre it's important to find the right size. The tyre should be 250kg-300kg for lighter and younger athletes and 300kg-350kg for heavier and professional athletes. Tyres below this range have too little training value. If an athlete finds a 250kg tyre especially difficult to work with they are not physically prepared for tyre training.
The article was aimed at fighters rather than strength athletes. I've enjoyed using a lighter tyre (150kg?) for mucking around/conditioning (not
CF) but I was wondering what Dave etc. thought of the above.
