Anonymous said: Just in regards to your gym post about size does not equal fitness. You are so very right! Although the other guy's regime of intervals of walking + jogging for 20mins is very effective in building a strong cardio vascular system and for cutting fat. This can be a lot more effective for certain body types than doing straight 45mins jogging and does not necessarily mean they are less strong or fit. Props to all those getting some exercise and pumping those heart huh!
