I see. Well my first tip to you would be to look into them. If you cannot find them at the store, perhaps the smithy or some other service can help you. Either weighted clothing or weights that can be worn under clothing can work quite well. For when you train in other gravity levels, you adjust to the extra output only for a limited amount of time. But weighted clothing will make it like living in a higher gravity, so you shall always be prepared, and your speed can become so much sharper.
