Jittery

My trainer has me on a new workout routine, since August 11th. (3 times a week, the other days I do cardio, and a variety of ab/core exercises)

Superset 1: (3x)
- Barbell Front Squats (12)
- Step ups (12 each leg)
- Single Leg Romanian Dead lift with Kettlebell (10 each leg)

Superset 2: (3x)
- Incline Chest press with barbell (10-12)
- TRX Deltoid Fly (10)
- TRX Bicep curl (10)

Superset 3: (3x)
- Lat Pull down (10)
- Plank with dumbbells, then alternating arm lifts (not a row, but rather move my hand with the dumbbell in front of me) 12x
- TRX Skull Crusher (10)

Dead treadmill push (20s, 1 minute break, 5x)

By the time I'm done with Superset #3, I'm already feeling a jittery, but by the time I'm done with the intervals, it's far, far worse.

I workout first thing in the morning, and eat:
* Banana
* Kind Nut Delight Bar
* 8oz of Pineapple Juice.

When I'm done, I eat 4oz of protein (chicken, steak, or a burger patty)

What can I do to prevent feeling so jittery? I have tried eating a bit more before the workout, without change. I have brought a sports drink with me, figuring the sugar in it would prevent that from happening. But, so far, this first week, I haven't been able to stop feeling jittery.

Any suggestions? I hope to speak with my trainer about this in the next day or so, but figured I'd ask the community.

Thanks,

Toine
