Very easily exhausted?

So today I decided to incorpate workouts other than cardio into my schedule. What I did today:

Wall Pushups
Sets: 2 Reps: 15
Boxer
Sets: 2 Reps: 15
Triceps Dips with Bent Knees
Sets: 2 Reps: 15
Isometric Biceps Hold with Resistance Band
Sets: 3 Reps: 1
Isometric Shoulder Hold with Resistance Band
Sets: 3 Reps: 1
Modified Pushups
Sets: 2 Reps: 15
Lying Triceps Lifts
Sets: 2 Reps: 15

Most of these were done with a resistance band.
Basically, by the end of this workout I was DEAD tired. I barely sweat (and I have overactive sweat glands) yet I felt like I could barely breath or move. Now, I'm not really out of shape (I walk everyday and I do cardio 4/5 times a week) so I'd think that being exhausted by such a simple workout is just a bit weird.
My question, really, is whether this is enough to be considered a complete workout? Should I be adding another workout on the same day?
Because while I do get exhausted, I still feel like the workout is really not enough.

It's a different workout than you are used to. You are using different muscles than walking. I'd give it more time- you'll likely improve. Just be sure you are well hydrated.
