Currently my cardio consists of 30 KM bike rides (takes about 70 mins) on my non-weight days (and Sunday, which is a rest day). This makes for over 3 hours of cardio per week.
Is this too much? I've been told that any cardio over abour 40 mins will be just training for endurance, and not burning fat very effectively.
Would I be better off just to shorten my rides to about 40 minutes?
Anyone have a lot of info on this?
