I currently live near a very steep hill I can run up for conditioning but I'm moving to university where it'll be very flat and I'll be training in a commercial gym so no sled or prowler. Would walking with a weight vest on be sufficient? The one I'm looking at weighs up to 30kg (66lb).
Further to my first question could you run with one or use it in other ways? I want to start doing a lot more loaded carries so I thought it could help with those.
