I need to eat MORE!

At one time, I was in the same boat as you -- needed to eat what seemed like an impossible amount of calories. Two things made it possible:

1. Frequent meals - 5-6 meals spaced throughout the day. Each one with about even number of calories. This is still difficult to eat that much though, and it takes some serious willpower to force it down your throat.

2. Protein powder/weight gain supplement. Two shakes a day were absolutely necessary to ingest the amount of protein I wanted and boost my caloric intake. One shake can provide over 400 calories in itself. (generally good calories, too.)

Only other thing you can do is drop the number of calories you need - which means resting more or slowing down your metabolism which really isn't an option. That's why those that are trying to gain weight, have to limit the amount of exercise/cardio they do. To gain weight fast, you need to phase your training - lots of weight/low reps and zero cardio other training until the mass starts getting added - then switch to a cardio trg to get rid of some of the fat that will accumulate.

I don't have any weights, are there any exercise that don't envole weights beside pushups and crunchs.
