Ground Training wings are designed specifically for training and teaching Paragliding and Paramotoring. they are typicly much smaller than a regular paraglider, 12-15 sq mtrs, and will probably have a low lift profile, allowing you to train in a greater range of windspeeds than a normal paraglider. These wings are great fun to play with on a windy day. Single skin designs are great on beaches as they do not fill with sand.
