Personally I'd ride uphill/headwind/sprint sessions out of saddle now its summer season... rather thanhttp://www.bikeradar.com/fitness/articl ... lank-26223
(keeping it inhouse to keep the BR fitness gurus happy)
which is an exercise for getting good at doing the plank..
There is no evidence that 'core' exercises make a jot of difference. I have seen one paper that suggests lateral knee movement is reduced, but with zero impact on power, injury or recovery time.
It's a fad. It does give you good looking abs though.
Any ideas on the top 3-5 best core muscle exercises you can do at home?
