Ever heard of the 85% Rule? According to this rule, aiming for 85% expenditure of energy instead of going all out (or at least creating that perception in your head), leads to better results in physical performance.
In New Zealand alone we discard 15.5 million tonnes of waste each year. That is 3,200kg for every Kiwi! Right now we only recycle 28% of this waste. The waste we send to the landfill is growing and becoming increasingly diverse and toxic. We therefore encourage reusing your old yoga mat and avoiding contributing to the landfill.
