Cardio

[Ferdo]

Is 20 minutes a day of cardio, 4 times a week on your off training days on a recrumbent bike good enough if you dont want to loose to much muscle but still loose some fat. Or does the body need 45 minutes?

sounds good to me. just make sure those 20 min. are high-intense.

well not really high intense but in that 20 minutes my machine says im burning 220 calories. I read somewhere that high intense cardio burns to much muscle mass and for example walking a low intense movement burns more fat calories. can anyone confirm this?

I'm sorry I can't find the link but do some research on HIIT(High Intensity Interval Training). Basically you bust your a#% for say 60 seconds followed by 1 or 2 minutes at a medium pace and then up it to max pace again. The session is shorter due to the intensity. Now you will burn less calories during this session, but more during the rest of the day. More cals burned (within reason) should equal more fat lossed.

yeah, that was why i said 'high intense'...cuz it'll burn more cals through out the day. i don't think it'll "burn" more muscle due to higher intensity level, just keep it short(15-20 min. worth).
