Good enough for what

I mean it depends on what you are doing, are you training for a marathon or something? No. But is it plenty for a warm up or post workout cooldown? Yes. However if its too easy for you bump up the pace or effort level

I just meant enough for me to lose a little weight

20 minutes is barely enough time to get your heart rate up and get a good workout in. Shoot for 30 or 40. You don’t need to go 5x a week. Try and do cardio you find fun! If you don’t find any cardio fun, watch youtube or tv or whatever on the treadmill or stairmaster.

Yes. It’s good enough. It’s better than doing no cardio at all. You can absolutely get ur heart rate up in 20 min. Your goals are likely diff than the other people commenting.
