No, I'm a hard gainer at age 29. According to my athletic-snack cookbook this means I'm "inefficient" because I waste a lot of energy as heat. I seem to be really hot a lot of the time, I handle cold temps well (as long as I have enough food), sweat like a dog in dry saunas (and do not enjoy them), and every girl I've been with says I'm too warm, so it seems to make sense.

Focusing on the big lifts (squats, deadlifts, bench press) made the biggest difference in my strength gains, and was when I added the most muscle.

OT, yes, but the struggle is real. When I really wanted to gain weight and I was lifting with good intensity I ate over 1000 cal surplus. But as far as wellness I assume that sort of excess is good for gaining muscle quickly but very bad for my long-term health so I doubt I'll eat like that again.

You must be under the age of 25 or so.

Please believe as you age, gaining weight will get easier and easier.

I'm currently trying to gain at age 35, I eat until I can't eat another bite and lift hard 3 days a week. Gaining weight comes slowly.

Stuffing yourself with solid food is indeed a chore. Shakes are an easier way. As is dumping butter and olive oil in your carbs. 1 teaspoon is 100 calories.

Funny I was in the same boat for first 2 years of working out, starting bulking with more oils, butters and shakes in addition to my usual 1 cup of carbs per day. Gained plenty of fat. Then got a few injuries in a row, lost intensity in the gym and now have more fat than I want!

I'd say I average less than 1 drink a month.

Drink more. You'll gain weight.

Gaining muscle is far different from gaining fat. Gaining "weight", regardless of composition, isn't what most people are looking for.
