Round 3 : Week 4 : Day 2

Today was generally an epic failure.  I thought after two rest days, I'd have today in the bag, but no.  For some reason I kept waiting and waiting and waiting to actually start my workout until hours after I'd eaten a measly 700 calories for breakfast and lunch.  As a result, I quickly came to understand that exercising on an empty stomach is all but worthless.  So here I am at 1 am eating dinner finally and feeling defeated.  Today was such a waste.  I keep telling myself that it was a learning opportunity, but mostly it feels like an opportunity missed.  I've had too many of those lately. 

FOOD: 
I ate a few too many mints (which I didn't log).  I also came up really short on fruits and vegetables for something like the third day in a row.  Not looking good here.  

EXERCISE: 
Because of the aforementioned circumstances, I got about halfway through my workout before I felt like I was going to simultaneously pass out and throw up.  Consequently, I have little to show in the way of stats...

• deadlift : 90# 4x3 dna
• squat : 60# 4x6 (+10#)
• lunge : 20# 4x6 dna
• bench : 30# 4x8 dna
• curl&ohp : 35# 3x5 (---)
• row : 40# 4x6 (+5#)
• pull : 30# 4x11 dna
• tricep : 10# 4x12 dna

LEARNED:
I need to eat something substantive, but light, about an hour before lifting.  Ideally it should have fats, proteins, and carbs.  Many recommend eggs, a granola bar, apple with peanut butter, or oatmeal. 

QUESTIONS: 

1. does hr need to be elevated for a cardio activity to count as exercise?  
2. if hr is not elevated, should that activity be logged/calories eaten back? 
3. am I eating enough calories (tdee calculators give me ~2000 calorie goals)?
