Brace
Place hands on a banister and lift legs as high as possible onto adjacent wall and lock into position.
1
Locate two banister uprights opposite a wall and stand on a step above the uprights.
2
Lean downwards and forwards, placing hands on tops of uprights.
3
Tense body and crouch down so as to transfer momentum when leaping the gap.
4
Swing across and transfer feet onto opposing wall.
5
Raise and spread feet as high as possible. Try and reach the ceiling.
Notes
It can work in another way: instead of using banisters for support you could use objects like a table or chest of drawers.
