EZA could you give us a little more info on Tabatas? Has there been any research done on tabatas vs several sets of varying distance sprints?
I, like many, first read about tabatas and have believed what i read ever since. Obviously i should know better, but guess I dont.
Can you please give us a little more insight into tabatas? Have they been proven to be less effective than other methods? Or have they just not been proven yet?
