7 reasons men over 45 with a bad back wake up sore without doing a single crunch

Since the "contraction one of 600" video went live, men in their 50s keep asking us the same thing: will it work on a back that's done with crunches? Here are 7 straight answers.

Crunches are a thing of the past, and your abs still get worked

1SignalA pulse reaches the muscle
2SqueezeThe muscle contracts hard
3ReleaseRepeat 600+ times
Contraction one of 600. All four zones fire together, and your spine never bends.

Most men who write to us used to train. Then the back started locking up, or a knee, or both. Crunches started to hurt, so they stopped.

The Kit works from the other side. A signal goes through the pad and the muscle squeezes on its own, the same way it does when you flex hard. You don't lift, twist or bend.

"I can really feel the contractions and it makes your breathe like you would in a workout." Rosie G.

That is the feeling the video was showing. Start low on the 19 intensity levels and turn it up when it gets easy. That's what we tell every new member.

Ape Born's 20-minute math, from the product page.

Crunches, curls and squats hit one zone at a time. You do a set, rest, then move to the next body part.

The Kit straps on in four places: core, arms, thighs and calves. Every contraction fires all four at the same moment.

A 55-year-old with a sore back is not doing 3,000 crunches. He can sit for 20 minutes. The day after, a lot of men tell us the same thing: they woke up sore in places they forgot they had.

Zero load on a bad back or knees, and you do it sitting down

At the desk or over the morning paper, sitting down.

A crunch bends your spine. A squat loads your knees. After 45, those two moves are why a lot of men quit training their core.

There is no weight to move and nothing to bend. The units do the squeezing while you watch the game or answer email. Keep walking and lifting if you can. This covers the days your back says no.

"I use it every day for 20 minutes while I am sitting in front of my computer and it's amazing how much it works out my abs." Warren D.

No sticky gel pads, and nothing to buy again

Strap on, no pads

Most cheap belts run on sticky gel pads. After a few uses the sticky stuff stops sticking, the signal gets patchy and you order more pads.

The Kit has no gel pads. You strap it on, give the pads a quick spritz from the spray in the box, and hit start. Nothing to peel off or reorder.

"The best part is it has velcro straps and not the gel pads like others." Rick S.

"I must admit that I thought all ab stimulators were gimmicks." Kevin K.

Six months later he wrote that it "amazingly helped with chiseling up my core even more." The Kit is FDA-cleared as a Class II NMES device, 429+ clinicians recommend it, and you can pay with HSA/FSA dollars.

The Kit comes with the 8-Week Transformation Challenge built by Olympic coach Jake Platt. You get it in the box.

A lot of members tell us what finally got them to try it: a photo of Jake Platt, an Olympic athlete, wearing the same kit with a group of regular people, many of them past 45. If he trusted it, they figured they could give it 20 minutes.

The most common complaint we hear about ab stimulators is "no instructions on placement." Where the unit sits decides whether you feel a deep squeeze or a light buzz.

The plan shows you where each unit goes, which of the 12 modes to run, and when to turn it up a level. Week by week, for 8 weeks.

Kevin K.

"I'm 60 and been a weightlifting coach, personal trainer, as well as a strength and conditioning coach for 35 years. (Former competitive lifter too.) At my age, I still like to experiment with things like supplements and equipment on myself. I must admit that I thought all ab stimulators were gimmicks. I purchased this and have been using it for 6 months. To my pleasant surprise, it has amazingly helped with chiseling up my core even more."

"I came into this situation of purchasing an EMS stimulator with skepticism. I've lift it all my life and I have never found an effective shortcut to ripping it up in the gym with free weights. I have never been more pleasantly surprised by a product that has to do with body building, as with this NMS wonder!"

Honest pacing

What the first 8 weeks look like

Week 1Sore the next day

You feel contractions you've never felt from a workout, in all four zones. Some men can't get past level 6 yet. Nothing to see in the mirror.

Week 2It starts to hit harder

Twenty minutes becomes part of the evening. You move up a few levels as your muscles learn the signal. Some men notice their shirts sit a little different.

Week 4Firmer when you stand up

The core feels tighter. Arms and thighs feel firmer when you flex. You're halfway through the plan.

Week 8Run the day-60 test

Time the plank again and compare it with day one. If you're not stronger, the 60-day guarantee covers you.

Week 4: firmer when you stand up.

Typical pacing from the 8-week program. Results vary. NMES supports training and good food. It does not replace them.

Honest answers to what men ask us most

Is it just a tingle?

It shouldn't be. If it feels weak, turn it up gradually over the first few sessions, strap the unit snug and flat on the muscle, and give the pads a spritz first. Most men say the arm and leg units feel strongest on day one. The belt takes a little more placement, which the plan shows you.

Isn't this another gimmick?

Kevin thought so too, after 35 years of coaching. It's an FDA-cleared Class II NMES device, and if you aren't stronger in 60 days you send it back.

Does it burn belly fat?

No, and we won't pretend it does. It builds and tones muscle. Food decides the fat on top of it. We tell every member the same thing.

Why not just go to the gym?

Keep going if you can. The Kit works alongside it, and many of the men above still lift or walk. It's for the core work your back won't let you do: seated, zero load, 20 minutes.

Isn't it a TENS unit?

No. A TENS unit blocks pain signals. NMES contracts the muscle. That's why you can be sore the next day.

Will it fit me?

All units close with adjustable straps. Extension belts are available for bigger waists. If an arm or calf strap is loose on a smaller limb, ask support for a size-adjusted band. You also have 60 days to send it back.

What's the free Elite Club trial?

It's the members' side of Ape Born: weekly live calls with Jake Platt, the member community, your lifetime warranty and monthly store credit. Your first 7 days are free. Keep it for $49.99/mo or cancel in one tap from your account.

Who is it not for?

Not for anyone with a pacemaker, anyone who is pregnant, or anyone with a hernia. If you have a heart condition or another medical concern, ask your doctor first.
