I have the 5kg and the 10kg and love both bags. The full body workouts available make working out fun.
This is a good one - nice features. What features, are they not all the same? No. Some have hard PVC pipe inside the three grab handles which makes them ... hard. So if it hits you, can kind of hurt. I got this lighter one specifically for kids, so I don't want that. Nice colour. Very good indeed. Been looking for years (5? 7?) for a good light one at a good price.
