So, two days ago spent about half an hour in the tunnel working on my head-up flying. I can hardly lift my arms to type. Freaking agony.
Anyone got some good tips for gym exercises to target the key muscle groups? Obviously my main problem is I'm flying with my arms too much but only yet more tunnel can cure that and I'm looking to make sure I get the most from my investment by targeting my gym work to ensure I can put the time in at the tunnel.
