Electrical muscle stimulation adds a light electrical impulse to voluntary movement. It reaches the deep fibres that movement alone engages poorly. The result: the whole body works at once, without heavy loads.

No. It feels like a deep contraction, a little disconcerting the first time. The intensity is raised gradually, with you, and set muscle by muscle.

Twenty minutes of training. Count on three quarters of an hour on site with the welcome, getting into the suit and the shower.

Once a week is enough to progress. A gap of forty-eight hours between sessions is needed: the muscle needs that time to recover.

Yes. Your coach starts from your actual level. There's no group to keep up with, no machine to figure out, no weight to lift.

No. It's actually the opposite: EMS is often used when getting back into exercise, precisely because it doesn't strain the joints.

The first sensations come after two to three weeks, visible changes usually after two to three months. Body analysis lets you check this objectively.

Little, compared with a conventional session. Most members leave after a quick shower, and many come on their lunch break.

Something to shower and change into. The training gear worn under the suit is provided by the studio.

No, it's not advised throughout pregnancy. After giving birth, you resume with the agreement of your doctor or midwife.

A pacemaker and electronic implants are an absolute contraindication. Epilepsy, severe heart conditions, thrombosis, hernia, cancer under treatment or acute infection require medical advice. A health questionnaire is filled in with you before the first session.

It increases muscle mass, and therefore energy expenditure at rest, and that expenditure continues after the session. But training doesn't replace nutrition: results also depend on what's on your plate.

Time, coaching and load. Twenty minutes versus an hour, a coach for you versus an open gym floor, and no heavy load on the joints.

The trial session commits you to nothing. Membership terms vary by option and by studio: they are presented to you before any signature.

Belgium's first 100% women-only EMS studio, on Rue Antoine Dansaert in Brussels. Clients, coaches, reception: women only, and each changing room has its own shower.
