Sandbags and kegs are a little easier to get hold of than Atlas stones. (Please, tell me you saw what I did there?) Many gyms these days have Powerbags or similar items, which are as close as you are going to get to a sandbag within a gym. If your gym does have these, avoid using the handles - treat them like an actual sandbag. With a keg or sandbag event you are likely to have to carry the objects a short distance before you load them. For training the carrying aspect in a limited space, even holding your sandbagsin the manner you would carry and walk with them is going to be of benefit. For the loading aspect, you’re unlikely to have a platform to load onto. But if you have something to load over (even a barbell set high on a squat rack), that’s a decent alternative.
