the heartrate's just as important as the time... i checked it out and it's 220 not 200 so an example
for someone who is 20 and has a resting heartrate of 70*
max heartrate = 220 - 20 = 200bpm
optimum heartrate for average excersise (as opposed to serious training that would usually go to about 80% of max) would then be 70% of 200 minus 70 so 130, so 30-45 minutes of excersising at about 100 would be minimum for good excersise, 120-130 would probably be better imo but if you're just trying to gradually improve health... the key thing is to keep your heartrate up for the entire time you're excersising, to rest afterwards and if you want to avoid a stitch don't drink too much during or immediately beforehand - don't start dehydrated, rehydrate well afterwards and sip during. just a few tips

this way you can also measure improvement in heartrate rather than the mirror, if you're resting heartrate is improving (ie getting lower) your fitness is improving and you're likely burning off the fat too.
*easily measured at the wrist or carotid [side of your neck], count it for 30 secs then x2 or get one of those cool watchy things that do it for you
