CORE PRO Backpack — 33L Gym Backpack with External Lifting Belt Storage
The KNKG CORE PRO is a heavy-duty 33L gym backpack with external lifting belt storage, built for weightlifters, powerlifters and serious strength training.
Carry your weightlifting belt securely outside the backpack, leaving more room inside for shoes, training clothes, knee sleeves, wraps, chalk and other gym essentials.
A Gym Backpack Designed to Carry a Weightlifting Belt
Traditional backpacks are not designed around the size and shape of a lifting belt. Packing a bulky leather or nylon belt inside can take up valuable space, press against your other gear and make the main compartment harder to organise.
The CORE PRO solves this problem with dedicated external weightlifting belt storage. Your belt remains secured to the outside of the backpack, where it is easy to access without taking over the main compartment.
- Save Internal Space: Carry your lifting belt externally and keep the main compartment available for the rest of your gym gear.
- Secure Belt Storage: The external belt attachment helps hold your weightlifting belt firmly against the backpack while you are on the move.
- Fast Access: Remove your belt without unpacking your shoes, clothes or training accessories.
- Improved Organisation: Separate your belt from clean clothes, electronics and smaller items.
Built for Weightlifting, Powerlifting and Strength Training
The CORE PRO is not an ordinary everyday backpack with a gym logo added to it. It is a purpose-built weightlifting backpack designed around the equipment used during demanding strength and conditioning sessions.
It is ideal for carrying gear to commercial gyms, powerlifting clubs, bodybuilding sessions, functional fitness training, weightlifting competitions and everyday workouts.
What Fits Inside the 33L CORE PRO Backpack?
The 33L interior provides space for a complete gym setup while keeping your lifting belt attached externally. Depending on the size of your equipment, the CORE PRO can carry:
- Weightlifting shoes, training shoes or sneakers
- A change of gym clothes
- Knee sleeves and elbow sleeves
- Wrist wraps, lifting straps and grips
- Chalk, tape and smaller training accessories
- A gym towel
- A shaker bottle or water bottle
- Headphones and training electronics
- Snacks and post-workout supplements
- Phone, wallet, keys and other valuables
Carrying your belt on the outside means more of the backpack’s internal capacity remains available for the equipment you need during your workout.
Upgraded Heavy-Duty Shoulder Straps
Gym equipment gets heavy. The CORE PRO features KNKG’s most heavy-duty backpack shoulder straps yet, providing improved support when the bag is loaded with shoes, lifting accessories, clothes and other training essentials.
The reinforced straps and padded back panel make the backpack more comfortable to carry between home, the gym, work and training events.
More Ways to Personalise Your Gym Backpack
An expanded hook-and-loop panel gives you more room to personalise the CORE PRO Backpack with patches. Add your name, gym, country flag, training club, competition patches or KNKG accessories to make the backpack your own.
The larger patch area also makes it easier to identify your bag in a busy gym, locker room or competition environment.

Gym Organisation Without Wasted Space
