Czech adjustable Heavy Weight kettlebag (training bag) 1–20, 30, 40 kg depending on the chosen variant

Our adjustable KETTLEBAG is made by hand in the Czech Republic in collaboration with top athletes from every discipline. It works on the same principle as a classic KETTLEBELL. There's no need to own ten kettlebells in different weights — this one kettlebag is all you need.
The kettlebag is also known as a training bag, and it is sewn using a special layering of material and reinforced seams to achieve maximum durability. A key advantage is the kettlebag's dual use. The first way is to use the handle, training with the bag just as you would with a kettlebell or a dumbbell. The second way is to attach the training bag to a belt with a chain, where the kettlebag takes the place of a weight plate or kettlebell.

Weights:
Unlike a classic kettlebell, you can change the bag's weight as you wish in one-kilogram steps. The package contains the kettlebag (training bag) and 20 one-kilo pouches filled with the same special weight filling we use in our weighted vests. This special filling prevents injury during training and stops your floor getting damaged if you drop the bag. The weights are compatible with the weights for our weighted vests and Heavy Weight weighted shorts.
Benefits:
- handmade in the Czech Republic
- high-strength material
- special layering of material
- reinforced seams
- ideal size and weight adjustment in 1 kg steps
- reduces risk during exercise
- handle for a more comfortable grip
- can be attached to a belt with a chain
Just as adjustable and versatile a product as the adjustable kettlebag is the Heavy Weight home fitness band set, which lets you adjust the resistance by attaching resistance bands while using it to train your upper, lower and core body all in one.
As we've already mentioned, you can attach additional resistance bands to the Heavy Weight home fitness band set to increase its functionality and range of resistance. The following bands can be attached to this set individually:
- resistance bands/strength bands/exercise bands resistance up to 7 kg
- resistance bands/strength bands/exercise bands resistance up to 13 kg
- resistance bands/strength bands/exercise bands resistance up to 22 kg
- resistance bands/strength bands/exercise bands resistance up to 29 kg
- resistance band/band Heavy Weight resistance approx. up to 45 kg
- resistance band/band Heavy Weight full set 7 to 45 kg
Short resistance bands/strength bands/exercise bands:
- mini resistance band/exercise band/mini band blue 7–9 kg
- mini resistance band/exercise band/mini band red 11–13 kg
- mini resistance band/exercise band/mini band black 13–18 kg
We also have extra-strong Heavy Weight resistance bands/exercise bands/strength bands, most often used for learning harder exercises like the MUSCLE UP, or other classic exercises when you're on the heavier side and your weight holds you back. Thanks to their strength, gyms also use them as a safety catch to stop the barbell falling during squats and prevent injury.
- resistance bands/strength bands/exercise bands resistance 27–68 kg SUPER HEAVY WEIGHT MUSCLE UP
- resistance bands/strength bands/exercise bands resistance 32–80 kg SUPER HEAVY WEIGHT MUSCLE UP
For both strength and conditioning training, working out on the suspension trainer is brilliant — you can work every muscle group in a completely different way from what you're used to. With the suspension trainer, your training takes on a whole new dimension. The other option for this kind of training is training with Heavy Weight gymnastic rings, available in two versions:
- gymnastic rings with a narrower grip
- gymnastic rings with a wider grip
-
Speaking of other products that can be attached to this set, we mustn't forget the Czech Heavy Weight resistance rope.
If you'd like to learn a brilliant exercise that few people can pull off, then the standing plank roll-out with a wheel is just the thing to show you stand out from the crowd.
To add another form of load when training with the fitness band set, weighted vests are a great option — you can choose from many Czech weighted vests in various weight options and designs, or try our new Heavy Weight weighted shorts.
You can boost your strength training by hanging weights from the Heavy Weight dip belt and attaching kettlebags filled with vest weights in various weight options:
- adjustable kettlebag (training bag) up to 10 kg
- adjustable kettlebag (training bag) up to 20 kg
- adjustable kettlebag (training bag) up to 30 kg
- adjustable kettlebag (training bag) up to 40 kg
Alongside weighted vests and adjustable kettlebags, other classic loads for strength as well as conditioning training include the adjustable sandbag in various weight options with 8 grip variants, or the specific training bag known as the Bulgarian bag, for strengthening your core and shoulders. Right after those come medicine balls/slam balls to build real explosiveness.
And what about adding an incline to your training? Almost every coach and physiotherapist includes one in their athletes' training. You get your incline with the slant board from Heavy Weight. And while we're on physiotherapists and coaches who use specialist kit, we should also mention the foam roller from Heavy Weight, ideal for recovery, rehabilitation and regeneration after every session.
For a higher level of rehabilitation and muscle release, there is the TOP GUN Heavy Weight massage gun, which releases your whole body in real comfort.

With the suspension trainer, your training takes on a whole new dimension. The other option for this kind of training is training with Heavy Weight gymnastic rings, available in two versions:
Another accessory is the MMA, boxing resistance bands, used by wrestlers, boxers and other fighters (e.g. Jiří Procházka of the UFC) — in fact by anyone who wants to improve their fitness. These bands will help you speed up your punches and kicks, and using them brings other benefits too.

In the summer preparation of ice hockey players — and other athletes too — the slide board, or skating trainer, features heavily. But being called a skating trainer doesn't mean that's its only use.

The Heavy Weight slide board is the answer for everyone.
Now that we've mentioned the training kit that will keep everything firmly in your hands, you should know there are also battle ropes/weighted ropes/training ropes, with which you'll build not just your forearms in an amazing way.

CrossFit, street workout, calisthenics and any other fitness training simply wouldn't be complete without SANDBAGS and KETTLEBAGS, which the army and other services have been using for many years.
An amazing tool for strengthening your core, lower body and upper body — arms, wrists and shoulders — is the Heavy Weight battle rope. Similar to the battle rope are heavy balls known as Heavy Weight medicine balls or exercise balls, available in several weight options at the ideal size. Or try the Heavy Weight Bulgarian bags, used by, among others, the wrestlers of the Czech national team.
NEW in the range are Heavy Weight weighted shorts whose weights are also mutually compatible.
So you can use Heavy Weight wrist weights or Heavy Weight ankle weights.
When stretching before or after training, you don't want to roll around on the cold, hard ground — you want to be comfortable and give all your attention to a proper, effective stretch. You'll only achieve that on our Heavy Weight exercise mat.
Where can you put all this training kit when you head out to train? In the Czech tactical backpack from Heavy Weight, for instance — everything fits in beautifully and it looks genuinely stylish too. You're also free to choose another backpack or gym bag — classic or with a custom design.
