I've found over the last few years that the amount of problems I've had with trigger points and muscle tightness has been unbelievable. It has really affected my fitness routine as it means I'm often having to modify my routine or cut out certain exercises altogether due to various aches and pains.
I can safely say I never used to have this problem years ago.
I do spend a lot of time sitting (for work etc) but I don't believe the amount of sitting I'm doing quite explains all the problems I've had... and I'm now thinking it might be partly down to my diet.
My diet has admittedly been shocking over the last few years... including way too much sugar, fried / processed foods and take-outs.
Could this be related to all the muscle knots and flexibility / mobility problems interfering with my fitness routine?
