Cardio once or twice a day?

[jpesc]

Is it best to do cardio for 40 minutes once a day or once in the morning and once in the evening at 20 minutes each for weight loss?

40 minutes once.

If you want to put in the time, you can do the 20 min after your training session at night - but yea - cardio on its own takes a while to kick things up. HIIT cardio might be another option for ya.

I like doing HIIT. I get as much work done doing it as I would two regular cardio sessions.
