The reason I like the sugarcane as a tool that one implements once every say two to four weeks as a replacement for one's typical high-intensity interval training is several fold. First of all, if you provide the right intensity in round 1 and round 2 and round 3, it is sure to elevate your heart rate substantially, and in doing so, improve your VO2 max, which is correlated with all sorts of important metrics related to health span, performance, and life span.
