there is a bunch of stuff on the net about how interval training (alternating high intensity with low intensity in bursts of between 30 sec and one and a half minutes) is better for you than medium intensity training.

there doesn't seem to be anything on how interval (alternating) training compares to high intensity training, though.

currently i do about 30 minutes of fairly consistent high intensity (keeping my heart rate near max by struggling with increased resistance or by increasing peddling speed). would i be better off switching from the current high intensity to interval training does anyone know???

thing is... i've actually been thinking i might be better to lower the intensity and increase the time to 40 or 50 minutes or... perhaps... keep the intensity and increase the time to 40 or 50 minutes.

people keep going on 'do you want to look like a marathon runner or a sprinter'??? (implilcation: a sprinter so do interval training). issue is... i'm a girl... i don't want to be built muscular like a sprinter particularly... i'd rather be lithe like a runner... (i want to burn more fat but i'm almost hitting up on the limits of how muscular i want to be - though i do want to continue with the weights).

thoughts welcome. peer reviewed stuff (that is relevant) is terrific too.
