General advice

Slendertone trainers are suitable for all adults, but some care is still needed. Don’t use our products if:

  • You have electronic implants (such as a pacemaker or defibrillator) or suffer from heart problems.
  • You are pregnant.
  • You suffer from cancer or epilepsy.
  • You’re under medical supervision for cognitive dysfunction.
  • You are connected to high-frequency surgical equipment.

Question: What does the sensation feel like?

Answer: When intensity increases, you feel a mild pulsing sensation followed by gradual tightening in your abdominals. The muscles should contract smoothly, hold in this position for a few seconds and then relax again.

Question: Can electrical muscle stimulation (EMS) training cause muscle soreness?

Answer:  Like any workout, some muscle soreness should be expected. Use a lower toning intensity if you’re experiencing excessive abs soreness.

Question: Why is the skin around my abs and sides red after a session?

Answer: Some redness is natural and should fade soon after training. If the redness is excessive, turn down the toning intensity. If the problem persists you can get in touch with our customer care team.

Question: The stimulation is a little uncomfortable. How can I improve comfort?

Answer: Ensure that the pads are positioned properly and pressed firmly on the skin. You can tighten the belt for a snugger fit too. Pause the session before making any abs belt readjustments. Check the intensity as well – you can always turn the intensity down to boost comfort.

Question: How do I know when I should replace my gel pads?

Answer: If the signal is weakening (even when the batteries aren’t dead), it usually means that the gel pads are wearing out. Adjust your abs belt to ensure correct, firm positioning just to be sure.

If this fails, it’s likely time to replace your pads. Their adhesive, hydrogel properties deteriorate after 20-30 sessions, so replace them after this period for the best toning results.

Question: Why won't my gel pads stick to my abs belt (they’re fairly new too)?

Answer: Ensure that the patterned grid-side of the pads is placed over the studs (with the black side on your skin) and that you’ve removed the protective covers. Before and after each session, make a habit of pressing the edges of each pad firmly onto the belt.

Question: I can feel tingling in my legs during toning. What should I do?

Answer: This means that the gel pads are incorrectly placed over your hip bones. Try moving the oval pads upwards and inwards (i.e. towards the center of your body). Don’t forget to pause your session first!

Question: What’s the difference between Slendertone and other brands?

Answer: Slendertone technology is patented, exclusive and clinically proven. Our tech had produced the only EMS belt capable of exercising all the ab muscles: the rectus and transverses abdominis and internal and external oblique’s.

Question: Can I use Slendertone Abs3 after having a baby?

Answer: Yes! We advise waiting a minimum of 6 weeks after natural childbirth or 3 months after a caesarean. We also recommend seeking approval from your doctor before starting a new toning program.

Question: Can I use an Abs3 belt if I have a belly button piercing?

Answer: We recommend removing any belly button piercings before every toning session.

Question: Can I use my Slendertone Abs3 during regular exercise?

Answer: Combining Abs3 toning with regular exercise can deliver even better results because your muscles are working harder. Walking, bodyweight exercises and yoga and Pilates are recommended. Use an intensity that’s slightly lower than what you’re used to.

Question: Why are my stomach muscles getting exercised but not the waist muscles?

Answer: People come in all shapes and sizes. This is why our gel pads positioning can be personalized for most body types. You can move the central pad slightly higher or lower than your navel. There are 3 size indicators on the belt as well, to help you target specific muscles according to the location of the nerves.

You can move the two oval pads to suit different waist sizes. Move them away from the central pad for larger waistlines or closer for slimmer waistlines.

Question: What is the warranty period on my Slendertone Abs3?

Answer: Your Slendertone Abs3 comes with a two-year warranty on electronic parts. If a fault develops, view our troubleshooting section or get in touch with our customer care team.

Getting started

Question: What do I need to work Slendertone Abs3?

Answer: You need your abs toning belt and controller, 3x AAA batteries, and one set of gel pads.

Setting up the Belt

Question: How do I assemble the shorts correctly?

Answer: Follow these simple steps to starting toning immediately:

  1. Lay your shorts on a flat surface so that the pad flaps/windows are open and the four metal studs are facing towards you.
  2. Take the four pads out of the bag. On one side there is a grid pattern; the other side is plain black.
  3. Remove the plastic from the patterned side and place the gel pads face down, so that the pattern completely covers the studs.
  4. Slide the shorts on for a firm fit around the buttocks and legs. It’s important that the gel pads can touch the skin, so wear underwear (like a thong) that allows this.
  5. Take the plastic covers off of the black side of the gel pads to expose the adhesive gel. Save these to protect your pads after each toning session.
  6. Firmly press and close the flaps, making a good contact with your skin.
  7. ‘Click’ the controller into place. Don’t force it in – ensure that the pin connector is the correct way around.

Question: What happens if the pads aren’t placed grid-side down on the studs?

Answer: The grid side evenly distributes the EMS signals from the studs. Incorrect placement results in results in less effective signal delivery and less comfort when toning at higher intensity levels.

Question: What happens if I don’t take off the plastic covers?

Answer: The pads use a water-based, adhesive gel that sends the EMS signals to the muscles, so they need to be taken off. Keep these covers handy to protect your pads after all Abs3 toning sessions.

Question: Can I move the shorts up or down?

Answer. Yes, but ensure that the controller is not connected and the four pad flaps are open, so that you can unstick the adhesive gel. Now you can reposition your shorts.

Toning

Question: I’m ready to train! How do I control my Slendertone Abs3 belt?

Answer: Now that you’ve set up your belt, turn on the controller by pressing and holding the power button for 2 seconds. Press both arrows up with your thumbs to increase the intensity. This starts the countdown automatically for your chosen toning program. To pause at any time, simply press the power button. Press again to resume or stop, or hold down to switch off your controller entirely.

We recommend that you tone while seated until you become accustomed to the sensation of EMS abdominal muscle contractions.

Question: What toning programs does Slendertone abs3 feature?

Answer: Slendertone Abs3 features 7 toning programs which can be used with or without exercise. Press the ‘P’ button to display all 7 programs. You cannot change programs during a session. To do this, switch your controller off and on again.

Your Abs3 has ‘auto-progression’, which takes you through a clinically proven set of parameters to provide a stronger core from 6 weeks. Auto-progression begins at program 1. Follow the sessions as prompted on your display screen

Question: How can I increase the intensity?

Answer: Press the arrows up with both your thumbs to increase intensity. Select an intensity that’s comfortable but still challenging. We recommend increasing this gradually over your six-week training plan to get the most out of every abs session.

Question: What intensity should I choose?

Answer: Each person has their own preferences so it’s impossible to recommend where your perfect starting point is. It should be comfortable but challenging and slowly increased during each workout.

Question: How many sessions can I do in one day?

Answer: We recommend two sessions each day at the most, but don’t forget to rest and recover if your muscles feel sore. It’s during these rest periods that your muscles are building strength.

Question: How many sessions can I do in a single week?

Answer: For the best results try 4-5 training sessions each week with rest days in-between. You can do more or less toning sessions, depending on your lifestyle or schedule and how much recovery time you require.

Question: Where can I view my toning progress?

Answer: Your controller stores total sessions and maximum, average and current toning intensity. To view this info, press the ‘i’ button. This will appear and revert back to the timer after a few seconds.

Question: How do I change my toning program?

Answer: You can change programs whenever you wish, but you will be starting all over again. You do not lose your overall session history, but you do have to restart from program 1. You can press the ‘P’ button at any time to change programs.

Question: What if my battery dies during a session?

Answer: Replace them immediately. You will, however, have to start your toning session again. Shop now for AAA batteries.
