Recently my brother bought a home gym machine that I use every second day, 3 sets of ten reps each on bench press/butterfly/lateral pull/two different leg exercises/bicep curls. And I also do some push ups, which I'm rubbish at (with 3 sets, I get maybe 25/21/18, but I am improving).

To compelement this, I am eating a lot more so I can build up strength, since I have always been pretty skinny/scrawny. At 5'11, maybe a year ago I was 145lbs/66kg. But I got over some OCD habbits that made me eat poorly, and by a few months ago I was 155lbs/70kg. Then when I really made a conscious effort to put on weight, by December I was 160lbs/73kg, and already I'm 172lbs/78kg just over a month later (having made the biggest effort the past few weeks).

The thing is I don't think that sounds particularly light weight now, but I still seem pretty skinny... I'm not even skinny-fat, no little moobs or anything.

Stuffing your face is a real challenge, makes me want to punch everyone that says losing weight is difficult. For example, yesterday I ate:

Spoiler Alert, click show to read: 
going by somewhat educated guesses below...

Breakfast 9am - bowl of bran cereal (150 calories, it's a fairly big bowl)
Lunch 12am - at work I took 5 boneless bits of chicken (550 cal) with chips (400 cal)
Second Lunch 7pm - 5 chicken thighs (500 cal), 4 slices wholemeal bread (350 cal), biscuits (125 cal)
Dinner 10pm - 2 chicken breasts (300 cal), chips (400 cal), beans (100 cal, no idea?), 4 slices wholemeal bread (350 cal), biscuits (125 cal), apple (50 cal) *usually dying by this point*
Supper 2am - bowl of bran cereal (150 cal), apple (50 cal), cookie (200 cal), 1 litre milk (600 cal)

= 4,400 cal


I don't get the lunch at work everyday so some days it's more around 3,500 calories per day going by my possible way off calculations... otherwise I stick pretty rigidly to the above. Obviously there is plenty of protein and carbohydrates there.

Q1 - Is this a good eating plan?
Q2 - With my exercise above, how much will I gain in a muscle/fat ratio?
Q3 - Is this a good rate to gain weight?
