Compound sets, super sets, drop sets, pyramid sets, and classic straight sets…just just a few different set variations you should utilize when performing your exercises.
All of them aim to construct greater, stronger muscles, however the research behind them can vary depending on the particular style.
Well, there is a latest special set on the town now, the cluster set, and it’d just be the perfect of all of them.
What’s awesome about cluster sets is you can adjust the best way you employ them to optimize various training goals.
More importantly, there may be loads of research to display its effectiveness, a lot so that you will probably be convinced you need to be using it in your program.
What Are Cluster Sets?
Cluster sets use a special set protocol designed to optimize muscle mass and strength gains while mitigating fatigue.
Essentially the most basic structure of a cluster set is to divide a single set into smaller “cluster sets” of just a few reps with temporary rest periods in between.
From there, the particular protocol can vary greatly depending in your specific needs. But here’s how it’d look. For instance you are alleged to do the bench press with 200 lbs for six reps. Using cluster sets may seem like this;
You might also do that with 2 cluster sets of three reps and even 6 cluster sets of 1 rep.
As well as, the remaining time can vary as well. With that said, the total variety of cluster sets is 2-5, with each consisting of 2-4 repetitions and separated by short rest intervals of 10-30 seconds.
After ending one full set, you’d rest as normal until you do your next set, whether 30 seconds or 2 minutes.
An alternative choice could possibly be to only perform one large cluster set. Let’s pretend you desire to perform the bench press using a 3X6 rep scheme. In total, this might equate to 18 reps. Subsequently, you would use 6 cluster sets of three reps or 9 cluster sets of two reps.
While barely different, one other similar method similar to cluster sets is what are called “rest-pause” sets.
Rest-pause sets were created by Nautilus exercise machine inventor Arthur Jones, then subsequently made famous by Mike Mentzer and his high-intensity training (HIT).
To perform rest-pause sets, you begin by performing your first traditional set to failure. You then rest 15-30 seconds followed by one other mini-set to failure which you then repeat for a total of 2-4 mini-sets.
Studies have shown that each cluster sets and rest-pause can improve adaptations, but neither tends to be higher than the opposite.¹
Regardless, this method enables lifters to keep up higher form and technique, handle heavier loads, and achieve greater muscle fatigue and hypertrophy because of increased time under tension.
How Do Cluster Sets Work?
When performing a conventional set of successive repetitions, fatigue progressively sets in until a lifter can not perform more reps. It’s necessary to know that fatigue is not necessarily a bad thing, because it actually stimulates the neuromuscular system and also plays a task in muscle growth.
Nonetheless, with the ability to do more work until fatigue sets in is superior for several reasons.
The primary is that less fatigue means the flexibility to lift more volume, which ultimately means more muscle growth.
As well as, mitigating fatigue can allow a lifter to lift more weight, theoretically leading to more strength gains. Further, by mitigating fatigue, a lifter can .
One more good thing about cluster sets comes from the intermittent rest between repetitions inside a set, which may alleviate fatigue. This allows an athlete to keep up consistent performance throughout the exercise session.
One in every of the first mechanisms that produces fatigue is the shortcoming to supply enough ATP, the molecule answerable for supplying energy to muscle contractions. Subsequently, the small rest intervals performed during cluster sets allow the body to supply more ATP.
Give it some thought as with the ability to stop to refill your automotive so you do not run out of gas on a road trip.
Research To Back Up Their Advantages
So, the idea behind cluster sets seems to support their use. But how do they work in actual lifting sessions?
Well, they work. Quite a few studies have shown that compared with traditional sets, cluster sets produce advantages through various mechanisms.
For instance, a 2017 study used three different set configurations for back squats. For all three, the full variety of reps was 12.
To do that, one traditional set used 60% of 1RM for the total 12 reps. One group used 3 cluster sets of 4 reps with 75% 1RM, and one other performed 6 cluster sets of two reps using 80% 1RM.
At the top of this system, the cluster sets saw greater total work and time under tension. At the identical time, the cluster groups had no greater loss in velocity speed or peak power, suggesting similar amounts of fatigue even with the larger loads. This suggests they allowed more work at the identical level of effort.²
More importantly, it showed us that using cluster sets would allow more total volume, which, when used over time, would likely end in greater muscle growth. You might also select to make use of heavier loads, which might theoretically end in increased strength gains over time.
One other study from 2013 made similar revelations. On this study, groups of athletes perform squats using heavy a great deal of 4RM. Again, the cluster set group allowed more reps, yet the athletes could sustain higher mechanical performance levels.³
The recurring result seen in all studies on cluster sets is fatigue reduction. You’ll be able to then use this lack of fatigue to your advantage: perform more reps, lift more weight, practice form, or finish your set with lower RPE.
Evidence for the mitigation of fatigue is so strong that researchers suggest more research be done with the elderly, special populations, and rehab patients!⁴
How To Utilize Cluster Sets In Your Training?
The one caveat for using cluster sets is that they are often performed with larger barbell movements, akin to the barbell back squat, bench press, deadlifts, etc.
No rule says you could not use these with bicep curls and skull crushers, but something like drop sets and even the rest-pause strategy we discussed earlier would most certainly be a greater alternative for those.
That said, you would use cluster sets to optimize the variable you are trying to realize based in your goals. You principally use the identical traditional variables after which apply them to the cluster sets.
For Power
If you happen to’re focused on increasing power, one option stands out. Use cluster sets of just 1-2 reps and longer intraset rest periods (think 2 minutes between full sets, NOT clusters).
This will let you perform reps with maximal power output while maintaining good form. Pair this with longer rest breaks of 20-30 seconds between clusters to permit the body to rest before each rep.
For Strength
If you happen to’re attempting to increase strength, your primary goal is to get more weight on the bar. This extra load ought to be accompanied by less fatigue build-up and lower RPE.
For instance, as an alternative of performing bench press with a 3X5 rep scheme using 200 lbs, you would perform bench press with 3 sets of (2, 2, 1) or 3 sets of (1, 1, 1, 1, 1) using 205 lbs.
For Muscle Growth
If muscle growth is your primary goal, increasing volume is your primary objective in your sessions, as that is the primary variable that drives muscle growth.
The most effective strategy to do that is to extend the full variety of repetitions. You might simply use the identical load but perform more reps to do that.
For instance, let’s pretend you are doing a bentover row. You would possibly use a conventional set of 150 lbs using a 3X8 rep scheme. You might do 3 sets of 9 reps or 10 reps using cluster sets. You might do that by doing 3, 3, 3 or 3, 3, 2, 2.
Cluster Sets Can Optimize Your Training
Those were just 3 examples of how you would possibly use cluster sets in your training, but there are various more. As more research is finished, we’ll likely discover more ways cluster sets could optimize our training.
Again, there isn’t any specific protocol to cluster sets which is the wonder behind their use. There’s also no complicated formulas to follow nor must you swap around weight plates. All you do is give yourself slightly rest every few reps and also you do more work of upper quality.
This simplicity, paired with their effectiveness, is what makes them such a strong tool to have in your arsenal!
