This is the question we hear most at a first session — often with some scepticism, because twenty minutes twice a week sounds too little to change anything. So what follows isn't just the number, but the reasoning behind it.
The short answer
Twice a week, 20 minutes each. That's how most of our clients train and it's what we'd recommend to you. The two sessions are not identical: one is harder and one is lighter, and there should be at least one rest day between them.

Why not more often
Muscle doesn't grow during training but during the recovery that follows. The session is the stimulus; the adaptation happens over the days afterwards. Repeat the stimulus before the body has responded to the last one and the effects don't add up — only the fatigue does.
With whole-body stimulation this matters more than in conventional training. The stimulation recruits a very large share of your muscle mass at once and bypasses the ordinary fatigue signals that would otherwise make you stop. The load is therefore greater than it feels during the session, and the recovery window needs to be correspondingly longer.
Why not less often
With a single session a week, the gap between stimuli is long enough that strength often only holds steady rather than building. Once a week is a sensible choice when that's all your schedule allows, or when EMS supplements other training — but as a standalone programme it progresses more slowly.
Why one harder and one lighter session
Two equally demanding sessions in one week would mean two heavy stimuli with little time in between, which is too much for most people. So we make one session harder and the other lighter: the lighter one keeps the rhythm and the movement patterns going without taking recovery time away from the muscles. Which is which, and how they sit in your week, is set by your trainer based on where you're starting from and how you respond.
| Day | Session | Focus |
|---|---|---|
| Monday | Harder | Higher intensity, longer intervals |
| Tuesday | Rest | Recovery; walking or stretching if you like |
| Wednesday or Thursday | Lighter | Lower intensity, technique and mobility |
| Remaining days | Rest | Recovery |
What the start looks like
The frequency doesn't change at the start — the intensity does. The first sessions run at a lower intensity and are shorter, because their job is to get you used to the impulse; from there we build the load gradually as we see how your body responds. Starting too hard is the one genuine risk with EMS, and deliberate progression all but removes it.
That's why it matters to tell your trainer how you felt after the previous session — even when the answer is that you felt completely normal. That information is what the next session is built on.
What about other training
EMS combines well with other training; it just needs sensible scheduling. Cardio, walking, swimming and stretching don't compete with EMS for recovery, so they can go in the days between. A heavy resistance session, though, counts as a hard session in its own right — if you have one in the week, one EMS session is adjusted around it.
If you want both, our COMBO package exists for exactly that: your trainer puts EMS and resistance training into a single plan rather than letting two programmes overlap.
„People often assume that training more often will get them there faster. In practice it's the opposite — the best results belong to the people who do their two sessions a week consistently, year after year."
