Heavy lifting and cardio. Really bad?

I don't think there's really a correct answer to your question. It all depends on your goals. It sounds like overall you're doing 8 workouts a week, 3 weights and 5 cardio sessions. This seems like a lot to me personally but if you can handle it, more power to you. If you're more interested in improving/maintaining your cardio then keep doing cardio as the bulk of your workouts. If you're more interested in being stronger/building muscle, switch to more weight training. Most people seem to recommend 3-5 days of heavy lifting a week for maximal results, so you're in the range. You do need proper recovery time especially if you're doing heavy compound lifts as you should be. Regardless of what you choose I wouldn't do all 8 weekly sessions as weight lifting, that's a good recipe for getting hurt or overtraining. Maybe convert a session or two over to weight lifting and see how your progress goes?

I don't think Chalean Extreme can be considered "heavy lifting". It's more of a cardio-based program with lighter weights (not knocking it, just stating the facts). It sounds to me you are doing a LOT of cardio. Excessive cardio whittles away what muscle you have, so my suggestion would be drop 3 of the cardio workouts (at least) and replace them with a true lifting routine like New Rules of Lifting. I think you will see faster results this way...I saw almost instant results from the program and I was already an intermediate lifter.

I wonder if you're thinking of Turbo Fire? CE is a weights program with HEAVY weights. Whatever heavy is for you.

To the OP: I'm just not sure the other cardio in necessary.

Maybe sleep in during the CE cardio days and use the gym days to do your own HIIT workouts at the gym? Then you'll get enough sleep to repair those muscles.

OP. you've lost 83 pounds.

whatever you're doing is WORKING!

but to answer your question. i'm doing both and not having any issues. i lift 3 days a week and do 60 minutes of cardio on non lifting days and 15-30 minutes on the lifting days. i'm still getting good strength gains.

i'm also doing nrol4w

Heavy weight training isn't determined by the amount of weight, it's determined by the number of sets and reps. If I recall, Challeen is what...12 reps or so? How many sets?

I'm sorry, but that's not really heavy weight training...I don't care how 'heavy' the weights seem to you.

If you can lift them more than 5-8 times in one set, you're moving into other areas of weight training entirely. Those being either body building, or endurance training.

Do not stop doing the weights if you're healthy enough to do them. Larger, denser muscle is generated by weight training. The denser and larger your muscles, the more calories they burn at rest.
Cardio pays off in the shorter term (i.e. during the exercise and for a period after, depending on intensity). Doing what you're doing sounds great, but I would be careful about rest times. All of the stuff I said above about muscle growth depends on the time for your muscles to adapt. Most information out in the world suggests 24 to 48 hr rests between weight routines. I would also agree that long periods of cardio can slow muscle growth (look at long distance runners - incredible athletes; no more muscle than is necessary to run efficiently), so make sure you balance your goals with the right exercise balance.

With your early starts, I would just make sure you get a decent amount of sleep. That 24-48 hr rest period is based on you getting a minimum amount of sleep, usually recommended as 8 hrs.
I always recommend dietician advice when doing a programme like yours, as well. You will have nutrition requirements greater than a casual exerciser and a dietician can help you work our what you need.

However, as an exercise junkie, I am thoroughly impressed. You sound like an athlete.

When I had a gym membership, I had a workout routine on the machines set by a trainer- I did that 3x a week and swim laps and/or walk on treadmill 2x a week. I had great results- probably more due to the weights and swimming. You have lost a lot of weight so you seem to know what's working for you so continue with your method.
