Have just completed week 1 but did not find it particularly easy - found myself counting lamposts and desperately hoping that the 60 seconds would soon be up! Am now concerned that I should be moving on to week 2 but don't know if I'll manage the 90 second runs if I cant do the 60 second ones. I should be able to do this! I'm not overweight (9 stone) have no medical problems and so am frustrated that I'm not managing a meagre 60 second run! Does/did anyone else feel like this?
