Say you are training individual moves, trying to become stronger/more powerful. You have two options
1. Use the smallest holds you can hold onto, and make the distance between the holds gradually bigger.
2. Use large holds with a huge distance between them, and gradually make the holds smaller.
Are you ultimately going to achieve the same thing with both approaches, or will they both have different effects?
...I suppose using a weightbelt is roughly equivalent to the first option, and changing the angle of the wall is roughly equivalent to option 2? Or is a weightbelt like doing a bit of both?
