Stuart Broad may have almost 400 Test wickets to his name, but that has not prevented the England seamer from attempting to improve his bowling action.
The 31-year-old, who has 399 Test scalps, will hope to reach a landmark only new-ball partner James Anderson has previously accomplished for England in the upcoming series against New Zealand.
But Broad clearly feels there is still room for improvement – tweeting two videos which show him walking through his bowling routine as he attempts to remodel his action.
“Working on my action to get more side on,” Broad wrote.
“More twist in my shoulders to get my front arm more towards the target, helping my feet align much better. Walk throughs give me a great feel of how my body is moving.
“Some balls come out great, some horrible, but I always say try different things in training cause if something clicks for you it can help your game, no one cares if you get it wrong in the aim for improvement!”
