Q: Do you think that daily low or high intensity cardio is a necessity for getting ripped?? Or once a week is good enough??

A: Daily cardio is almost certainly a bad idea if you are doing weight training on top of it. Your body needs rest. Taking at least one or two days a week off from all exercise is a good idea. I would recommend either 2-3 sessions of HIIT per week, building up to 15 minutes/session (search for HIIT on my site if you are not familiar with it) or 2-3 sessions of regular steady pace cardio of 20-40 minutes each.

If you have a specific time of year when you want to look your leanest you can try to increase your cardio in the weeks immediately before, as a sort of final push. But doing daily cardio year-round in addition to weight training is likely to lead to overtraining and injuries.
