Not really, unless you're incredibly unfit/obese. For a decent effect from cardio you want to be close to 70-85% MHR (maximum heart rate) which at 25 should be around 195 so 70-85% is about 135-170.

HIIT is my favorite type of cardio (and proven most effective for physique building purposes) where i get near 85-95% MHR (boxing/grappling).

For general cardio purposes, 20 minutes on the bag or going for a run every 2-3 days is enough, start off easy and work your way up.
