truSculpt flex vs. EMSCULPT: Head to head

If you’ve landed here you probably have a few questions…

It takes a very long time and a lot of commitment to build muscles. When you workout muscles are stimulated by contractions and once a threshold is reached the muscle fibers tear. This triggers your body's natural reparation process, which repairs the fibers, resulting in an increase in size. 

Even though working out is great and highly encouraged the actual physical motion can now be replicated with technology. And to no ones surprise, technology can achieve the same thing but faster and much, much better. 

The EMSculpt and truSculpt fleX are both FDA approved muscle sculpting treatments administered to tone muscle. Both are non invasive procedures, require zero incisions or injections, and result in no downtime at all, just muscle soreness. 

With muscle sculpting treatments there is no strain on ligaments, bones and joints meaning that the body doesn't need to produce energy. This means there is significantly less lactic acid build up, which is also why there is limited soreness post-treatment. In many ways it's bypassing the body's natural function and thus eliminating the related side effects while also being more effective. 

Moreover, results can be seen immediately for both treatments. They can both be used to target specific, hard to reach areas and drastically increase the results you would get from going to the gym.

However, although these two treatments can help you achieve the same goals, they use very different mechanisms. 

The EMSculpt

The EMSculpt device delivers electromagnetic energy to muscles in the treatment area causing them to contract supramaximally.

In other words, the machine causes muscles in an area to contract and experience more stimulation than would be possible with a manual workout. As a result, muscle is built while also allowing for fat reduction and body contouring. 


Studies have been shown that the EMSculpt can help patients loose up to 20% in fat and gain 15% in muscle mass in every targeted area. 

It also has no side effects or downtime.


While the EMSculpt activates motor neurons there is no specific focal point. This means that it is less specific and effective a targeting muscle fibers. 

Due to the electromagnetic stimulation technology muscles can only be stimulated in one one direction. i.e. it doesn't twist and turn the muscle like the fleX it just performs a linear contraction.

This means that the EMSculpt doesn't stimulate the muscle from end to end and only has one mode, whereas the fleX has three.

The EMSculpt is very expensive, and can range upwards of $5000 for a full treatment, which also consists of many sessions and only 2 areas can be treated at once.

The truSculpt fleX, on the other hand, uses Electro Muscular energy to specifically target muscles and force algorithm controlled contractions by way of electrical currents.

Each fleX session is the equivalent of 54,000 repetitions per muscle group targeted. That's a lot of repetitions! A full fleX treatment yields the results of 3-6 months of consistent High Intensity Interval Training (HIIT).

This process allows for very specific muscle fibers to be targeted. Up to eight muscle groups can be targeted at a time. Unlike the EMSculpt, the truSculpt fleX is best for individuals who are relatively lean.

It was explicitly designed to help increase muscle mass, unlike the EMSculpt which also serves to burn fat. However, Cutera also makes the truSculpt iD, which is a more effective non-surgical body sculpting treatment.

The truSculpt flex usually consists of 4 treatments, costing about $600 per session. Patients Like the EMSculpt, there is no downtime or side effects. 

The fleX allows for multi-directional stimulation, which is allows for more authentic replication of weight training leading to significant gains in muscle thickness, size and mass. 

There are also three unique treatment modes prep (for those that don't work out), tone and sculpt. A package of 6 will include 2 of each and a package of 4 will include the latter two.

Up to 8 areas can be treated in a single session and results are sustained for 3 months.


The truSculpt fleX is a newer machine, which means it can be harder to find a provider. Not all medical practices are willing to dish out hundreds of thousands on additional equipment.

What makes the truSculpt fleX better than the EMSculpt?

Choosing between the truSculpt fleX vs. EMSculpt is hard, because they're both pioneers in muscle sculpting technology.

However the fleX is the most recent pioneer and its technological developments have significantly improved the efficacy of this type of  treatment. Its use of Mono Polar RadioFrequency energy allows for the most targeted muscle stimulation ever seen. 

The EMSculpt is good but wasn't designed for the sole purpose of muscle mass increase and its use of electromagnetic stimulation simply isn't as effective. An EMSculpt treatment is the equivalent of 24,000 repetitions, whereas a fleX treatment is equivalent to 54,000 repetitions.

For those looking to remove fat while also adding muscle definition the EMSculpt is not a bad choice. There are also other options out there for fat removal like CoolSculpting or truSculpt iD.

However if you want both less fat and more muscle the truSculpt iD and fleX combination is probably your best bet.

On average the EMSculpt increases muscle mass by 16% and reduces fat by 20%. Whereas the truSculpt iD leads to 24% in fat reduction and the truSculpt fleX leads to a 33% gain in muscle mass.
