Hey all,
I'm currently focusing on getting a straddle press with straight arms. So far I can do a bent arm legs together press. Here's a video of it (after the first press):
I feel like the only thing limiting me to do a straight arm straddle press are my hips, i can't seem to lift them higher then this:

I realized now this is not really a good angle.

I can't lift my hips higher than that (note: this is not me).
So what would be the best exercises? Currently I'm doing bent arm presses and hanging leg lifts. My straddle L is quite weak so I'm guessing that it would help a lot if I would strengthen it.
