You get a different kind of workout using a GripSack…

Working out with a GripSack exercise sandbag

If you like heading out for long, drawn-out gym sessions, you’ll hate GripSack workouts.

Because, with GripSack, you get a proper full-body workout in as little as 15-mins — at home.

And, if you enjoy endless reps and sets, and fiddling with machines and weights, you won’t get that from GripSack either.

With GripSack, you put your whole body to work from the moment you pick it up. That’s why three short workouts a week can…

yesBuild muscle that gets noticed

yesBuild strength you’ll actually use

yesBuild your fitness, so your body doesn’t hold you back

It’s so effective, people will think you work out more than you do.


You were built for this…

People compare GripSack workouts to farm work. Because, every exercise feels like honest hard graft — and your whole body feels it.

Only the fittest people can do twenty-five minutes with a GripSack. It will leave your muscles shaking, heart thumping and you gasping for air!

Your workouts will feel less like “performing exercises” and more like simply putting your body to work.

Your body was built to lift, handle and carry. GripSack strengthens those abilities, while building muscle and endurance.

What happens when you train with a GripSack?

1. You build muscle that keeps you young

With GripSack, your strength training is more like grappling with life. You grip the bag, not an easy strap or bar. Lift it clean off the ground. Your whole body gets to work — all 600-plus muscles pulling together.

2. You stop your grip fading with age

Remember granny or grandpa wrestling with pickle jars? Grip is where the rubber meets the road! That’s why a GripSack sandbag exercises your grip throughout your workout.

3. You keep getting stronger and fitter

GripSack changes weight in seconds, so every workout keeps pushing your progress. Start heavy, then drop the plate when you need to. Or start lighter and add plates as you get stronger.

@MiniWorkoutDad proving GripSack builds muscle all over your body

A question from GripSack’s longest user…

Steve - @miniworkoutdad

“What if you just did 75 minutes a week?”

Would it make any *real* difference (to how you look and feel — and feel about yourself)?

Hi — I’m Steve (@MiniWorkoutDad!) and that’s the question I asked myself, aged 51. Why 75 minutes? Because, that’s all the time I could give. If you have a minute, I’ll share what I discovered…

First though, I’m wondering: are we alike?

Are you one of those people who lives/ loves fitness? To be clear, I’m not. Who has time to take good care of family, live just a little AND obsess over how they look? Not me!

So, why not just kickback and enjoy getting old instead?

Well, here’s the problem: wanting to *enjoy* getting old. You see, maybe you’ve not noticed yet, but there’s this sneaky process that begins breaking down your body in your 30s. It’s called Sarcopenia and it is dissolving 10% of your muscle every decade. Worse, helpful muscle gets replaced by harmful fat.

So, if you’re hating how you keep gaining a few pounds every year…

No matter how ‘good’ you try to be! That’s Sarcopenia in action. Losing muscle means losing the thing that burns more calories. The more muscle you lose, the less you can eat without getting fatter.

But, losing muscle is more serious than getting a little squidgy.

Because, that fall you have in your 70s — the one that breaks your hip and starts the downward spiral? That started with losing muscle now. And losing muscle increases your risk of developing cancer, Parkinsons, Alzheimers and heart disease.

You can only stop Sarcopenia ruining your life by telling your body to stop dissolving muscle. Even better, I discovered you can go one step further and build muscle back in just 75-minutes a week. And, get fitter and happier about the way you look at the same time!

That’s why I’m doing 75-minutes a week with my GripSack.

I’m not going to pretend it’s easy — the workouts are tough. But, 75-minutes at home is something even I can stick to. And, that’s why, aged 54, it’s still the only fitness I do.

GripSack works for me and it could work for you too.

So easy to fill and use…

Why you get a better workout with GripSack

  • You develop grip strength — a vital asset for living and indicator of longevity
  • You progress faster when trying a heavier weight is 25 seconds away — no messing with sand
  • You can do more exercises with a smaller-sized sandbag that still weighs heavy
  • You can grip or hold this bag (in several ways), without losing control and risking injury
  • Its grippable shape avoids carpal tunnel syndrome or tendonitis in the wrist (other sandbags can trigger)
  • It’s a soft weight, ideal for shouldering, putting behind for neck, hugging in carries and it doesn’t hurt on impact!
  • You get true from ground up lifting and no slop/ or jerkiness from slack in the straps – because there are none!
  • Having a quality bit of kit that just feels right is a great incentive to workout!

adding or removing weight is easy with a GripSack


Choosing your size

There are three sizes. The first number in the product code represents an achievable sand-filled weight in pounds. The second number is the max weight with external plates added (lb).

35-5050-7065-90
Max filled35lb/ 16kg50lb/ 23kg65lb/ 29.5kg
Max weighted50lb/ 23kg70lb/ 31.75kg90lb/ 40.8kg

Weight plates are easily and securely strapped on using the high strength webbing, featuring all stainless steel fittings.

All bags are supplied empty for you to fill with sand to your weight requirement.

Order the bag size that accommodates some weight progress, without being excessively large. Excessively empty bags will be floppier and not handle as well.

Please note: GripSacks are NOT ‘slam bags’. They are robust and designed for the rough and tumble of workouts, but not for repeated throwing or slamming onto the ground.

Gentlemen: it’s likely that you’ll be working out at 50-plus pounds (>22.5kg), once you get some workouts under your belt. The 50-70 version will give you the opportunity to grow into heavier workouts by easily adding weight plates.

If you’re a bigger guy, who already has some strength training under his belt, you might want to go straight to the 65-90 size. But, you should be confident about starting at over 57lb/ 26kg.

Ladies: a typical workout weight would be 35-40lb. But, if you are already doing heavier resistance training, the 50-70 is satisfactory down to 44lb of sand.
