Good Cardio workouts?

[Bluecast]

So for the second day in a row I did a good workout.
Almost the same as yesterday. 3 sets of 5 min on the Treadmill except today a steeper incline.
Rowing machine but instead of 2 5 minute sets I did 1 10 minute set.
Then I added 5 inclined situps.


So here is what I am asking anyone know good cardio workouts? Just remember I can't to lifting wights or anything.

Good for you man. Keep it up. Got a pool around you can use? Swim around that for a good half an hour and you'll be spent for the whole day. Personally I get bored of the gym stuff. Would rather do something more recreational while "working out" Ride a bike. Play some catch. Basketball. Light yogging..

Nah no pool. This is just the gym in my building. I'm trying to lose 40 pounds.

I like riding my bike around the city or going for a long walk. Mostly stuff were I can listen to music in my headphones and rock out around town.
Now that I see AXM mentions it I wish I could go for a swim. Its been so long.

I wish I could do water arobics

For me the best type of cardio is indeed running. Cardio is pretty easy to do as all you need to do is get your heart rate up. I usually mix things up for cardio, unless I am going on a long run. Jump rope, jumping jacks, cycling (not that leisure sunday morning ride crap... do enough work to get your heart pumping. Going on a trail with my dirtbike is fun and does get my heart rate up.), and burpees are a few things you can do to keep your heart rate up.

I know you said you cannot lift weights, but can you do body weight exercises at least? If you can run, I dont see what would prevent you from doing anything else with your body. If you can, here are a few things you can do to help build muscle mass in the following areas. Gaining muscle is great for weight loss because the extra muscle burns calories while you are just sitting around playing video games.

Arms:
Pull-Ups (If you cannot do many pull-ups, do negative pull ups to build your muscles up)
Push-Ups
Rope Climbing using just your arms
Dips

Legs:
Lunges (if those are too easy do walking lunges)
Squats (again if they are too easy, do one legged squats)
Step ups

Abs:
Crunches (there are a crapton of articles that say this is terrible for your spine, but I must've done at least a million crunches in my life and my back is just fine, whatever)
Any type of plank
Leg Raises

I would suggest reading this and create a routine that works for your fitness level.

[Who Really Cares?]

Cycle might be easier for you than running and of course walking. A good walk a day will help.

Easiest and fastest way to lose fat is interval training. Sprint (whatever is your fastest) for 20-30 seconds, then power walk or jog for 1 minute. Can be done on any treadmill. Also lay off the dorito's and sugary gatorade/powerade.

Ah yeah I gave up all that stuff months ago. I gave up soda 6 months ago.

I can give you my diet if you'd like. I got it from a nutritionist and lost 12 pounds in 1 month with it so far.
