145 days straight P90x3 and now P90X Hi All,

I'm not on a 145 day run of exercising every day with Tony Horton, prior to this I ran through a full round of T25, plus a few extra weeks of Gamma and a lot of running.

What I'm finding recently is I lack flexibility. I hope this might improve as I go through X but is there any tips to help increase this, other than the yoga and x stretch I am already doing?

Thanks
