Increase running distance or speed?
Hey guys,
For the past few months my cardio has consisted of doing a 6 k run in around 30 mins, out in the open, 6 days a week. This used to kill me when i first started it, but now i hardly feel it, and thus feel that it probably doesnt cause much in the way of weight loss anymore. So i was thinking bout changing it up, but am not too sure whats the best change to make? Should up the distance or keep the same distance but try to run faster and faster? which is better for fat loss?
Cheers
P.S. My 'HIIT' consists of 2 days of soccer every week...
