Yes. That would be more than enough to build a great deal of strength useful for day to day life.
Probably won’t help you deadlift 400lb or squat 400lb or anything, but it’ll definitely get you stronger.[/quote]
Sorry misread the site, the sand bag can go up to that but the waterbag is 120lb.
The reviews say because the water is moving about a lot that it is really unstable so it makes the weight feel heavier than it actually is and works muscles that you wouldn’t work with free weights.
But what im worried is that i will get stronger but in a more functional way and without the impressive physique that comes with lifting weights… if that makes sense… no bulging eye popping muscle gains just overall strength increase.
Edit: 120;bs with available bags for filling but can go up to 200 lb if i purchased another few filler bags.
