MICE: “not hard enough for me”; “I might have increased the max heart rate just to push myself a bit”; “more intensity, and less overall time. My schedule is so packed that 60 minutes a day can be difficult—I would like to work out 30 minutes a day with more intensity for the 30 minutes”; “Heart rate parameters”; “I will exercise with a higher heart rate for varied lengths of time”; “I will exercise with a higher heart rate for varied lengths of time”; “…outdoor like to increase intensity a bit”; “Yes.
