If I work out in the morning is it ok to eat a big breakfast first? In the evening before I go home what should I eat and how much before working out? what time of the day is it best to work out?
i never ate 'big' before working out..can't imagine how that would impact pullups with a gut full of meal eating big is kinda discouraged in general, as you're supposed to eat small meals all throughout the day although to be honest, i would have a small meal (protein/carb shake+fruit) 20-30 minutes before lifting in the morning, eat small meals/snacks (tuna fish etc) throughout the day, and eat like a pig at dinner as for lifting times...it's kinda like common sense i generally have more energy and drive when lifting in the morning after a long day at a physical job and on the streets, it takes a little more effort and motivation most of my knowledge comes from just being a serious lifter and competitor. when you lift, lift and lift, you have no choice but to schedule around your lifestyle to get in workouts, and you begin to see how stuff impacts performance. you become your own personal trainer.
I eat big and frequently when trying to bulk. I started bulking this week and transitioned from leangains. I find it's easy to eat a lot so long as I am eating the right foods.
Understand the difference between foods that have "Fast burning" carbs vs Foods that have "slow burning" carbs. Before a workout it is ok if your have protein and slow burning carbs. Slow burning carb sources = fruits and veggies and oatmeal. Fast burning carb sources= white foods like cane sugar, potatoes, rice, white bread ect. (Even though Fruits and veggies have simple carbs they still burn slow because of their fiber content.) After a workout you have about a 45 min window in which your muscle receptors are open to receive plenty of nutrients. You want to take full advantage of this by eating fast burning carbs first to boost your insulin spike, then have your protein shake, along with any other supplements you have. Keep it simple like a bagel and a protein shake. Avoid fatty foods during this 45 min window. Personally I don't take my multivitamin during the 45 min window because fat is needed to absorb some of the vitamins, but a do take my other supplements during that time. Long story short is that fast burning carbs cause an insulin spike which would be desirable after a workout not beforehand. Plan your carbs accordingly
For me, it's the opposite because I'm diabetic. I need the sugar because, even if my glucose reading is normal before working out, I will crash because I still have insulin (from my shot the night before) in my system. The combination of exercise and the insulin makes me sink fast. I learned this the hard way (draped over the counter at Planet Fitness scarfing down Tootsie Rolls from the complimentary bowl).
