Quarantine Hotel Requirement

Bought it for my hotel quarantine. Highly recommended when only choices are small rooms.
Not only that, I continue to use it at home now as well without hassle of going to the gym. A portable Bulgarian Bag.
Only issue is that I can't fully empty the bag when packing for always worried that water would leak out.


Super versatile, very easy and fast to set.
Lots of exercise variety and you can fill it up with water as light or heavy as you want! FULL RECOMMENDED

Even better than expected

It takes 2 minutes to set up, and makes your workout so much more challenging, especially for your core. I truly love it. Easy to carry and easy to adapt for everyone. 🔥🔥🔥

Loved it!

Purchased this so I could bring this to my quarantine hotel and continue working out. True lifesaver! Would recommend for anyone who travels as well and wants to stay consistent with their strength training. Love how it’s easy to set up and the feeling of having to balance the water makes my regular workouts much harder.
