Volume: How many sets should I do?
While there are some low volume proponents (e.g. 1 set to failure per exercise), most of the available evidence currently convenes on there being a dose-response relationship between training volume and muscle-building. This means that, up
to a certain point, doing more sets likely leads to more muscle-building.
The range for most people is 10-20 sets per muscle per week. While further gains may occur beyond this range, this is
unlikely to be required for those in their first few years of training, and it's certainly not the best choice if you have never even tracked your response to a given number of sets.
Using
very-high-volume approaches (e.g. 30, 40, even 50 sets) may be appropriate in specific cases, but are probably best reserved for the advanced trainee with technical mastery and specific goals (e.g. bringing up a stubborn muscle group that never gets sore and can handle a lot of volume).
For most trainees, we suggest starting off your programme in the 10-15 sets per muscle range (less for beginners). You can then creep this up over time if required, particularly if you're not getting any muscle soreness, you feel you have more to give, and you have already nailed both effort and technique.
Intensity: How many reps should I do?
Over the last decade or so, there have been repeated studies on the question of rep-count and muscle-building. The results have been very positive, as we now know that a broad range of rep targets can be used with similar muscle-building outcomes.
In most cases, anywhere from 5-30 reps can work well. For the most part, we plan training with 8-15 reps, and deviate from this for a smaller portion of training volume.
Practical considerations are quite important in determining your target. Doing sets of 20 on an exercise like dumbbell lateral raises can work really well, but try doing sets of 20 on deadlifts. You will quickly learn that not all reps are the same, and thus rep targets need to be prescribed with practical considerations.
For heavy compound movements that involve more total muscle and generate more systemic fatigue (e.g. deadlifts, squats, overhead presses, etc.), we generally stay closer to 5-12 reps.
For lighter movements involving less total muscle and lower fatigue (e.g. bicep curls, lateral raises, calf raises), we are far more comfortable climbing to 20 reps and beyond. With that said, most sets tend to still be in the 10-20 rep
range.
The key equalising variable between rep ranges is that you are taking sets close to failure. Your reps should be slowing, and especially on those high rep sets, your muscles should be
burning. Most of the time, you should have no more than 1-3 reps left in the tank at the end of your set.
Frequency: How many
times per week should I train each muscle?
Training frequency is a very useful tool to enhance your gains. We discussed volume above, and even if you keep your volume for a given muscle the same
in a given session, repeating that 2-3x per week can give you much greater total volume.
For example, 6 sets for chest in a given session can be performed with focus and excellent quality. But, 6
sets per week probably isn't the optimal level of volume, especially for most advanced trainees. What if you did that on Monday and Thursday? Well, now you have doubled your training volume, and because you had 3 days between, you can probably have a session of equal quality once again.
For this reason, we tend to view frequency as a vehicle for volume. I would much rather see someone spread 18 sets for a given muscle across 2-3 sessions, versus doing all 18 sets in one session. You've probably experienced the drop-off in quality that tends to occur later in a high-volume training session, which makes me skeptical that those second 9 sets are going to be as effective as doing them
when you are fresh again.
Frequency isn't a magic bullet, but for me, it's an excellent tool to improve your volume distribution and thus training quality. As a bonus, higher frequencies also
enable more opportunities to improve your skill and technique, which is advantageous for those looking to focus on specific movements (e.g. squat strength) on top of muscle-building.
With all of that
said, we haven't even mentioned what exercises you should do?!
