How to install a yoga swing in my living room?

My roof trusses are all 2x2's, so I only have 1.5" of wood available to anchor into. The roof gains it's strength by the design of the trusses, but there's not much strength there to use as an anchor point. I wouldn't trust it even if was just my wife hanging from it. What you're looking to do is transfer all 125lbs of weight into 2 single 3/8" mounting points that are anchored into narrow pieces of low grade pine lumber.
