Workout Description

This workout plan is designed to help you shred fat and get in shape in only 12 weeks. This might sound like hype, but it's not. The following plan is not easy. It starts slowly, but builds rapidly.

Every detail of your diet and training for the next 12 weeks will be laid out for you. You will be told exactly what to eat, how much cardio to do, and how to weight train.

The goal is simple: lose fat, maintain muscle mass, get in shape and transform your physique as much as possible over the next 3 months. You want to not only look better, but have the fitness level and strength to match your new body.

12 Week Program Expectations

Over the next 12 weeks your goals and expectations are:

  • Fat Loss - To lose at least 10 pounds of fat.
  • Muscle Mass - To maintain, or even gain lean muscle mass.
  • Conditioning - To be in amazing shape; perhaps the best shape in years.

The 12 Week Diet Plan

Each week will consist of 3 different types of eating days.

  • High Carb Days - 1 day per week
  • Moderate Carb Days - 3 days per week
  • Low Carb Days - 3 days per week

You may structure these days in any preferred manner. I suggest keeping the high carb day for special occasions. That way you can attend family functions, or eat out with friends, and indulge a little more than normal.

It should be noted that calorie intake can be adjusted based on metabolism. The follow changes are recommended:

  • Men 40+ - Reduce daily calories by 300.
  • Men 20-25 - Increase daily calories by 300.
  • Women 40+ - Reduce daily calories by 200.
  • Women 20-25 - Increase daily calories by 200.
12 Week Eating Plan for Men
  • Week 1 - 3 low carb days with 2300 calories, 3 moderate carbs days with 2400 calories, 1 high carb day of 2700 calories.
  • Week 2 - 3 low carb days with 2200 calories, 3 moderate carbs days with 2400 calories, 1 high carb day of 2700 calories.
  • Week 3 - 3 low carb days with 2100 calories, 3 moderate carbs days with 2400 calories, 1 high carb day of 2700 calories.
  • Week 4 - 3 low carb days with 2000 calories, 3 moderate carbs days with 2400 calories, 1 high carb day of 2700 calories.
  • Week 5 - 3 low carb days with 2300 calories, 3 moderate carbs days with 2300 calories, 1 high carb day of 2700 calories.
  • Week 6 - 3 low carb days with 2200 calories, 3 moderate carbs days with 2300 calories, 1 high carb day of 2700 calories.
  • Week 7 - 3 low carb days with 2100 calories, 3 moderate carbs days with 2300 calories, 1 high carb day of 2700 calories.
  • Week 8 - 3 low carb days with 2000 calories, 3 moderate carbs days with 2300 calories, 1 high carb day of 2700 calories.
  • Week 9 - 3 low carb days with 2300 calories, 3 moderate carbs days with 2200 calories, 1 high carb day of 2700 calories.
  • Week 10 - 3 low carb days with 2200 calories, 3 moderate carbs days with 2200 calories, 1 high carb day of 2700 calories.
  • Week 11 - 3 low carb days with 2100 calories, 3 moderate carbs days with 2200 calories, 1 high carb day of 2700 calories.
  • Week 12 - 3 low carb days with 2000 calories, 3 moderate carbs days with 2200 calories, 1 high carb day of 2700 calories.

Protein intake should be a minimum of 180 grams per day. If you are a bigger guy, or have a fair amount of muscle mass, then eat 200 to 220 grams of protein per day. If you eat a little more protein the drop your daily fat intake to make up for the calories.

Fat intake should be approximately 20-30% of your daily calories. Once you have determined your daily calories from proteins and fats, fill in your eating plan with carbohydrates.

Also, you are allowed up to 10% of your daily calories from dirty foods/junk foods. You do not have to eat any junk if you prefer. This option exists as a convenience, should you be battling a craving, or attending a social gathering where you would prefer to have a small snack.

The 12 Week Cardio Plan

It doesn't matter which form of cardio you use for these 12 weeks. Pick something that gets your heart moving, be it treadmill, elliptical, or swimming.

The first thing you will notice about this cardio plan is that it starts slow. That's ok. Right now you are out of shape. This program is designed to get you in shape over the course of 12 weeks.

Be patient. Trust the plan and stick to the plan. After the end of 12 weeks your level of conditioning may surprise you.

During the first 6 weeks take at least one day of rest between cardio workouts. After week 6 it is recommended that you perform cardio using a 2 days on, 1-2 days off pattern.

  • Week 1 - 3 cardio sessions. 5, 8 and 5 minutes.
  • Week 2 - 3 cardio sessions. 8, 10 and 8 minutes.
  • Week 3 - 3 cardio sessions. 10, 12 and 10 minutes.
  • Week 4 - 3 cardio sessions. 12, 15 and 12 minutes.
  • Week 5 - 3 cardio sessions. 15, 20 and 15 minutes.
  • Week 6 - 3 cardio sessions. 20, 20 and 20 minutes.
  • Week 7 - 4 cardio sessions. 20, 22, 20 and 22 minutes.
  • Week 7 - 4 cardio sessions. 22, 25, 22 and 25 minutes.
  • Week 9 - 4 cardio sessions. 25, 27, 25 and 27 minutes.
  • Week 10 - 4 cardio sessions. 27, 30, 27 and 30 minutes.
  • Week 11 - 4 cardio sessions. 30, 35, 30 and 35 minutes.
  • Week 12 - 4 cardio sessions. 35, 40, 30 and 45 minutes.

So I don’t see a flat bench workout. All that is stated is an incline bench routine. Is this how it is supposed to be?

What do you recommend as a regimen after the 12 weeks (and at desired body fat percentage) for maintenance?
I don't have access to Leg Press, Leg Extension etc machines. What alternatives (free weight) do you recommend?

Hi Josh!

I am very grateful for the plan you have created. I am 20 years old, 75 kg weight and 183 cm growth. I've been trainging for a year and I've lost over 13 kg. I wanted to try something new. That's how I found your plan. My needs, including the caloric deficit, are approximately 2,300 calories. The same amount is entered in your plan, so it looks like it is created perfectly for me!
I have a question about the level of carbohydrates on particular days. Do I understand it correctly? I calculated the distribution of macronutrients and I mean mainly carbohydrates. Is this division okay?

WEEK 1

1. Low carbs days -> 180g P/60g F/260g C [2300 kcal]
2. Mid carbs days -> 180g P/60g F/285g C [2400 kcal]
3. High carbs day -> 180g P/60g F/360g C [2700 kcal]

Regards! :)

Hi!
I have a quiestion.
The calories which I burned during cardio, should I count to the daily calorie intake?
For example, if i Burned 300 calories durong cardio and I have to eat 1500 calories a day, is it allowed to eat 1800 calories?

Hi, thank you so much for this great guide. I think I might be confused on the nutrition plan though. As far as I can tell you fill in the remaining calories minus 20-30% fat, and in my case 120 G protein with carbs to figure out your daily carb intake. On the plan, some of the days with lower calories say moderate carb, and the higher calorie day says low carb. Would you mind helping me clarify. Just making sure I didn’t miss a piece of information to help me figure out daily carb allotment on low carb vs. moderate and high carb days.. This is a great guide and I’m super excited to give it a try. I have been staying around 1200 calories for a long time and was doing a ketogenic paleo diet still unable to lose weight. I have hypothyroid and adrenal fatigue for which I am taking supplementation. I just worry if upping my calories could cause weight gain. Any help you could give me would be greatly appreciated!

Hi,

Would it be okay if I added my own personal abs programs to this workout? I like to do a couple of abs workout right after I finish the basic program. Would that be over training?

Cool, so I'm going into week 10 and results have been pretty good. Not amazing, but good. I didn't expect to come out looking like mark wahlberg or anything lol. I started at 204lbs and now I'm hovering around 198lbs but the recomp is evident. I see the calories are slowly coming down overall while the cardio is ramping up so I'm interested to see what happens in the next couple weeks. I haven't deviated at all. I'm using eatthismuch.com to plan my meals, drinking plenty of water, and I'm doing my cardio after lifting on m, tu, th, f). I'm sure lack of sleep isn't helping (only getting about 7-8 hours of so-so quality sleep).

For cardio, I'm just doing some low impact hamster wheeling. 3.5 mph on the heart rate mode so that it keeps me in the 80-85% max zone for the duration of my session. So that's around 140-145 bpm for me. I feel like 142 is the sweet spot. 145 starts to grind my joints a bit.

Couple questions:
- Does that cardio routing seem adequate? I can't really do HIIT or anything, and I don't think I'll have to start running to keep my heart rate up for a few more months probably.
- What would you suggest I follow this 12 week plan with? I'm culminating this 12 week plan with a week trip to Hawaii, but when I get back, I'm probably only going to take a couple days rest before wanting to hop back in. Should I just do this plan again? Cut? My instinct tells me to keep the same plan but start changing up the exercise implementations (e.g. switch stiff leg DL for regular DL; switch dumbell presses for barbell presses, etc.) Recommendations or a solid followup plan would be great! Thanks!

Hey Jeremy

I was browsing the comments section and came across your post. I’m in the exact same boat as you. Just heading into week 10 and not noticing much changes over the last couple of weeks. And I’ve added more cardio. I’m hovering at 205 and wondering how I can change things up and what my next step is. Let’s share tips to help us both get out of this funk [email protected].

I'm on week 6 and kicking some serious ass. I'm 38 and I didn't even know I had ABS but hey there they are. This plan is great and I'm still learning proper nutrition as some days haven't been perfect., Rather than just quitting because I've failed, I've used it as a learning experience and got right back on schedule. I've been taking weekly pictures and I can't wait to share my results. Thank you for this great post. I'm curious if you have suggestions on pre/postwork meals. I wake up at 5am for gym at 5:30am and usually have a whole white tortilla with a couple pieces of deli meat, or a shake consisting of 160calories:34% Carbs 17%fat 34% protein. 5:30 start plan of the day, cardio (yes I got bored with 3days :)). Done by 7am and usually have a protein shake consisting of 200 calories 20%Carbs27%Fat53%Protein. And then three hours continue on with my daily craze. This seems to work for me, but so did a large pizza and beer. .I'm I hurting my success by eating like this pre/post workout? Thank you again.

Hi Shaun,

Depends on your goals. If you don't have fat to lose and want to build muscle, increase your calorie intake. If you want to maintain your current physique, no need to change your calorie intake.

i dont understand the cardio sessions still, can you explain it a bit more ?

No Profile Pic
Posted Sun, 05/20/2018 - 17:42
Jeremy

I honestly think it's just about getting those sessions in. Since you monitor progress weekly, it's really just about those extra calories burned during the week. What I mean, is: it doesn't matter. Just get the sessions done sometime during the week. For example, do them in the morning and your lifting at night, or do them after your lifting, or do 3 of them on "off" days. Just don't do them immediately *before* lifting sessions or you're gonna have a trash lifting session...

I'm going into week 10. For a couple weeks, I was doing them on wednesday, saturday, sunday... so I was in the gym 7 days a week which got exhausting and you need to rest. Plus, when it ramped up to 4 days per week, I HAD to do at least one session on a lifting day. I recently switched to doing them all on lifting days to free more of the week up. It actually wasn't that bad. I'm in the gym for up to an hour and a half now, but it's fine. I thought doing cardio after lower body days (tues and fri) would seriously suck, but it's fine. As an added benefit, I read that you're basically burning out glycogen during the intense parts of your workout, meaning your cardio session afterwards is probably burning off more energy from fat.

Which days and what workouts do we have to do low carb, high carb and moderate carb days? Also, the cardio your attached workout plan doesn't make sense when it says on top to start off witht 5-10 mins of cardio, but the file says 30 mins? So which one is it?

Hey,
Just wanted to ask, you’ve written number of calories that you need to get every day, but the exercises are included ?
For example can I eat 2600 cal and burn 300 so I finish the day with 2300 or I need to get 2300 cal from food only?
Thank you

Hi Dan,

It is difficult to recommend a broad diet as diet is highly individualized and will vary from person to person.

Start here to find your calorie needs: https://www.muscleandstrength.com/tools/bmr-calculator

Then go here to determine your macros: https://www.muscleandstrength.com/articles/how-to-calculate-perfect-macros

Then finish up here for an idea of what to eat as part of your diet: https://www.muscleandstrength.com/articles/how-to-create-a-bodybuilding-...

In the plan it's just food calories for the day.

But as mentioned, the plan is very generic and you'd be better off forming a diet to meet your needs with the resources provided in the past comment.

Hi Ahmed,

Focus on one goal at a time.

All workout programs work to do those things depending on your consistency with the program, diet, sleep, and lifestyle outside of the gym.

Be consistent. Body recomposition takes time. Sometimes it can take A LONG time. Training is a marathon, not a race.

Hope this helps!
