Metabolic resistance training (MRT) combines structured circuit training with progressive weights for time-efficient fat loss and muscle growth. World-renowned physique coach Gareth Sapstead explains all you need to know, as well as introducing two MRT workouts to try for yourself.
The best training approach to achieve a total-body transformation, build muscle and get lean doesn’t always fit with the time you have available. Ideally you would lift weights in a progressive manner to build muscle and strength, while following a balanced diet for sustained energy and maintaining a moderate calorie deficit diet to burn body fat. But we can’t all spend two hours a day fitting everything in. So what’s the alternative? Enter metabolic resistance training, or MRT for short.
MRT will get you great results, helping to build muscle and shed fat, while being as efficient as possible – with workouts completed in 30 minutes or less. So lace up your best gym shoes and get ready to achieve optimal results in no time at all.
What is metabolic resistance training?
MRT is a form of circuit training with progressive weights, in a way that challenges you metabolically. It’s not your typical circuit training, though, which often involves a poorly thought-out workout structure combined with sloppy exercise form. No, metabolic resistance training has structure and purpose, and that’s why it can produce fast changes in body composition while keeping you injury-free and feeling athletic.
You perform five to six exercises in sequence with minimal rest, using the same resistance device – for example the same barbell, dumbbell, or kettlebell. To make things as efficient as possible, the weight also remains the same throughout the entire circuit. That is why exercise selection and sequencing is important.
How to structure metabolic resistance training workouts
There are two ways to structure your repetitions. Option 1, which is most common, is to keep the reps the same for each exercise and throughout the circuit. For example, every exercise is done in the 6-8 rep range.
Option 2 is where you’ll vary the repetitions based on the exercise and how challenging it is for you. This helps to accommodate for the same resistance being used, and works to better apply an appropriate load to each movement. Option 2 is what we’ll be using, since it is the smarter approach and real-world tested for achieving the best results.
Considering this is a high metabolic stress technique, it’s wise to choose your exercise order carefully – we will explain how later in the article. With MRT performed correctly, with good lifting technique, your workouts will require less space, less equipment and less time.
Benefits of metabolic resistance training
- Fat loss
MRT puts a very high demand on to the anaerobic energy systems (both ATP-PC and glycolytic). Using these energy systems for repeated bouts of exercise is associated with growth hormone release and activating lipolysis, aka fat loss. - Prolonged calorie burn
Metabolic resistance training causes a lot of excessive post-exercise oxygen consumption (EPOC). Because of that your resting metabolic rate will spike and continue to burn energy even after the workout is over. This is sometimes known as the ‘afterburner effect’, and it’s crucial for any effective fat loss plan. - Muscle growth
MRT is a form of resistance exercise, so by using a routine of progressive overload you’re developing stronger bone, connective and muscle tissue. Since muscle is metabolically active tissue, that means even more fat loss. - Muscle sparing
Traditional forms of cardio exercise, when overdone, can promote unwanted muscle break-down, especially when in a caloric deficit. MRT on the other hand will have a muscle ‘sparring’ effect.
How to create a metabolic resistance training programme: five golden rules
There are a few key rules when designing a good MRT program. If you do a quick internet search, you’ll find a variety of different routines and ways to do them. But as previously stated, why settle for average styles of circuit training when we at MF can do better? So these are your new laws of MRT programming.
1. Do ‘high skill’ exercises first
Exercises should be performed in descending order, from the most technically demanding to the least demanding. You should ideally try and place the most technical exercises towards the start, where fatigue is lowest. The complexity will also depend on your movement capabilities and just how ‘complex’ it is to you. As an example, an Olympic lift variation is more complex than a front squat, which is more complex than a bent-over row or a lunge.
Placing every exercise in order of complexity is not always possible, however, when we try and follow the rest of the rules. But always start each circuit with the most complex. For the rest, if it doesn’t work in the order you’ve put it in, don’t think twice about scrapping it and trying a different order.
2. Use a non-competing exercise order
Non-competing exercises are those that don’t rely on the same muscles. The benefit of using this exercise order is simple: while one group is working, the others are resting. Given the fact that many exercises you’ll be using work multiple muscle groups all at the same time, don’t get too hung up on specifics here.
Generally, try to alternate a pushing exercise with a pulling exercise, or an upper-body movement with a lower-body movement. Or if you have two lower-body exercises back-to-back, make one more knee-dominant (e.g. Bulgarian split squats) and one that works your hips more (e.g. Romanian deadlifts).
3. Select a weight based on your weakest exercise
MRT circuits should be relatively short. The entire appeal is that they’re brutally effective but brief. By imposing a 10-rep max weight limit – based on your weakest exercise – in a circuit, you ensure that you will never go above 6-8 reps, which allows form to stay tight and effort to remain high.
For example, if a barbell overhead press is your weakest exercise in the circuit, choose a weight that is no heavier than what you can press for 10 reps.
4. Set rep ranges rather than specific rep goals
There seems to be an unwritten rule in circuit training that every exercise needs to be done for the same amount of reps or for the same amount of time. Instead, you should set rep ranges (e.g. 8-10) versus specific reps (e.g. 10) to provide a suitable challenge for every exercise in your circuit.
By sticking with the same weight throughout, it only makes sense that the reps have some flexibility.
5. Do not set the weight down for longer than 15 seconds
You can complete each exercise without ever letting the weight touch the floor. Or, you can put it down and reset every time. It makes no real difference, although if grip is an issue or your technique gets sloppy, then a 15-second reset between exercises would be a smart move.
How to get started with metabolic resistance training
Select your exercises based on the above rules, making sure that you’re using no more than your 10-rep-max for your weakest exercise.
Next, test the absolute maximum reps you’re able to achieve with the same weight on each exercise. These can be your warm-up sets, before doing your actual working sets with challenging weights and reps.
Program your reps for each exercise based on your test. Pick a target that leaves a little in the tank. If my max reps were a 10 out of 10 for effort, then I want to pick around a 5 or 6 out of 10. Remember, MRT is about lifting with purpose, good time under tension and good form. It’s not just about moving the weight and counting your reps, so keep your weight high and reps low.
Try the below routines out for yourself. If they flow well, are challenging you to the right level, and above all feel good for your body, then add them to your roster of weekly workouts.
