How To Gain Up To 10lbs Of Lean Muscle In 8 Weeks

This video and blog post is for hard gainers, looking for lean muscle gains, or anyone who wants to gain lean muscle really quickly.

Today we focus on the two things you can do to gain ten pounds of lean mass in the next 8 weeks. Even if you have the goal of fat loss, it is also important to the have goal of maintaining your muscle mass. Why is this? The more muscle mass you have, the higher BMR you have, the more fat you burn at rest, the easier it is to sustain weight loss, and the easier it is to maintain your body composition.

When your goal is to gain and sustain lean muscle mass, you never want to sacrifice muscle for fat.

Let’s talk about the two things that will get you there. If you follow these two things, you’ll gain 10 pounds in 8 weeks…

  • TDEE
  • TUT

What is TDEE

TDEE is your Total Daily Energy Expenditure. This is a number of calories burned with your activity level throughout the day. What does this number mean for your gains? This means if you want to gain 10 pounds, you have to eat above this number every single day.

For example, your TDEE is 3,000. In order to put on mass, you have to eat more than 3000 calories a day. It takes 3,500 calories extra to experience 1 pound of weight gain. If you consume that for seven days, 500 extra calories as day, times 7 days, that brings you to an extra 3500 calories a week. That excess will gain you 1 pound in a week.

⚡ Related: Use a BMR Calculator to figure out your TDEE.

On a side note, when we say consume extra calories, this doesn’t mean eat cupcakes, donuts, HoHos, and Twinkies. That’s not what we talking about here. When you eat crap you will gain mass, but it’s very little lean mass and a lot of fat. There are people who do this and put on a lot of bulk, but then they have to cut. To cut they drop calories and then they lose the weight and are right back to where they started. This creates a teeter-totter when you try to bulk with garbage. The goal should be lean mass, which requires you to consume quality calories. If you follow our social media accounts you know what this means. Use our Macro list and grocery list for good references of foods you should be eating.

Let’s move on to the second thing.

What is TUT 

TUT is Time Under Tension. What does that mean? This means the amount of time your muscles spend under tension during any given set.

For example, bicep curls. You add up the time your muscles are in the concentric phase (tension curling up) and the eccentric phase (tension uncurling) in seconds. You total that up and multiply by the number of reps you do. Where you need to be is 40 to 70 seconds TUT every given set. If you have three bicep exercise and four sets each for each exercise, you add up the three exercises times four sets. Every set should be 40- 70 TUT. This is the same when you train legs, shoulders, chest, back, or calves.

The goal is always TUT 40-70 for lean muscle gains. Lean muscles gains also mean achieving muscle hypertrophy. You need to use muscle hypertrophy methods in order for them to grow. That happens at 40–70 TUT. People think heavy weights and fewer reps is the only way to do it. Reps do not matter. You have to manipulate the reps. Sometimes you do really light weights and more reps and you still get there. Sometimes you do heavy weights and fewer reps, but you can still get there. Doing fewer reps means that you only do 6, but you do them very slowly.

We know this works because Michael has done it, and thousand of clients have done it with him. If you follow this you will get very close to these lean muscle gains in 8 weeks. Some people with get more gains than others because some people are harder gainers than others. Another factor is if you have been working out for a long time and the number can vary for your potential gains. If you just started working out and you are a hard gainer, you can hit this goal. You will be happy and getting these results as long as you also eat clean, whole foods, that are as close to nature as possible.

If you feel you have hit a plateau, or are seeing little or no gains and are looking for an effective workout, HIIT MAX™ Elite can help you get the results you want. The program takes the guesswork out of your workouts by showing you what exercises to do, how many reps to do, and the rest times in between. The workouts are set in calendar format and you just choose the day of the month you want to start and follow along while we keep track of your process. Each month the workouts change and progress with you so that there is no plateauing and you gain lean muscle each month.

This is just one of the many benefits of HIIT MAX™ Elite, and with membership, you also get nutrition guidance, a forum to communicate with our trainers and other members, as well as an ever-growing list of great music for you to enjoy during your workouts.

Be patient. Stay the course. And, let’s get fit together!

    You teach 1 gram of protein for 1 lb. of body weight. Here’s my question. I’m 70 years old. I work out 3 to 4 times a week, but I don’t do the high intensity workouts. I do things that are more appropriate for my age. In this scenario, does the amount of protein still need to be 1 to 1, or can I consume less protein per body weight because of my age and workouts of lesser intensity?

    • Thanks for reaching out David. I love that you’re staying so active. I would shoot for .8g of protein per lb of body weight and consume around that number each day if possible. Thanks for reaching out.

  2. Hallo Michael

    The youtube bideo is good stuff! I just want to know, why everybody is talking about IIFYM?

    • I’m not an advocate about IIFYM (if it fits your macros) because one should be focusing on the quality of the food they are consuming and not just eating anything as long as it fits your macros. A car runs on gas and some cars run on premium gas. If a car requires premium gas and you keep putting regular gas in it because you’re looking at it’s still gas, over time it will wear on the car and it won’t function as well as if you put the proper gas in the car. As a human our bodies work best off of eating whole foods as close to nature as possible. Eating whole foods over other foods you’ll see you’ll have more energy and just feel overall a lot better as a whole.

  4. Hi Michael
    I’m a teenager working out 3-4 times a week with bodyweight exercises (Méthode Lafay) and HIITing or doing cardio 2-3 times a week.
    I’m following you from a very long time and I admire your work *_*
    I just have a question about this article. If I understand good, that means I can do max reps push-ups/squats/pull-ups (slow or fast tempo) for 40-70 seconds and eating as described and gain lean mass ??

    • Yes you want to keep tension on the muscles each set for 40-70 seconds. Mixing it up as well using slower reps such as bench press taking 5 seconds to lower the weight down and then exploding up from the bottom. No need to set an exact number of reps but going to your maximum effort and making sure you are in the threshold of 40-70 seconds is key.

  5. Do you have any recipes to go along with the meal plans?

  6. Logan Herrera says:

    Dear Michael,
    I am a 16 year old looking to put on a couple pounds of lean mass, without much gain in fat. This is because I am a wrestler and will be needing to cut for season. I weight train 2-4 times a week and have high intensity practices 3 times a week. With all this working out it has been tough to get all of the calories I need to actually gain weight. Could you give me some insight?

  7. I was just curious, is there a set percentage of calories that should come from each macro? I’ve seen a lot of things that say 40% carbs 30% protein and 30% fat and other variations. Is there a way that you recommend to gain lean muscle?

  8. Thanks for the advice. Keep up the good work.

  9. OMG, Im so frustrated! I work out 6 days a week, HIIT and weightlifting and I cannot get cut!! What am I doing wrong?? I have your six pack finishers info, using the fooducate app which I hate!! i cant find anything good enough to eat.

    Please help Michael

I want to hear from you
