whats the most cardio you have done on a consistant basis?

[velvett]

I used to do stairmaster for 75 minutes 5 days a week, then I went to rollerblading the Central Park Loop in NYC.

Until a foot injury a few months ago I did do 30 mins cardio - elipitcal or rollerblading 4 times a week.

My gym has a heavy bag and a speed bag, so what video(s) would you suggest????

Look for some videos on Everlast website or Ringside. I actually have an old thread about bag work if you can't find it pm me and I'll be happy to give you my beginner routine
