Powerbags & Sandbags

Sandbags and powerbags (also called core bags) shift their weight as you use them, perfect for functional fitness and CrossFit. This flexibility helps to strengthen your core, as the flexing of the bag will force you to adjust your body accordingly. Your abs will get a good workout as well.

Gym sandbags and powerbags were initially developed for elite sportspeople like the England Rugby World Cup winning squad, but are now used by anyone who wants to train hard with weights in an effective and versatile way. They're particularly popular for CrossFit and functional fitness workouts.

The flexing of the sandbag and powerbag means that the shape is constantly changing. This unpredictability means you have to use your whole body to keep control. This is the fundamental difference between sandbags and powerbags, and your usual fixed position free weights like CrossFit dumbbells, kettlebells and medicine balls. The unique structure of the bags will allow you to burn calories, build muscle, and lose fat.

The range of exercises possible with core bags is vast including lifting, dragging, squatting, and carrying. In fact, there are currently over 150 different powerbag exercises listed, many of which have their own progressions and regressions. This means you have variety, which is key in strength training.

What Weight Bag Should I Buy?


Our powerbags and core bags are available in a range of sizes that are suitable for an array of workouts:

5kg: Ideal for rehabilitation, an introduction to weight lifting, and performing dynamic movements with a partner.

7.5kg: Useful for jumping exercises as well as weight lifting exercises.

10kg: Good for weight lifting and diagonal and rotational moves, and for walking lunges and sumo squats.

15kg: Good for dynamic weight lifting exercises and core stability.

25kg and 30kg: For working large muscle groups hard.

35–50kg: Good for building muscle and will for working out with a partner as two or more people can carry the bag. This has made them popular with rugby teams and in military and boot camp-style training.


Many of the weighted sandbag styles available include wide mouth openings that allow you to add the sand in. Many models will be available up to 50lbs in weight. Some sandbag designs will also allow you to adjust the inner weight with different combinations of sandbags, a useful feature if you want to use different weights.

When buying a sandbag, check out the ones that use free flowing sand. These will shift and mould better than those that use pellets or packets of sand, therefore increasing the unpredictability which is the uniqueness of this product.

You should also check that the sandbag you are buying has inner bags to ensure that they are durable and won’t start leaking sand!
