Morgan,
Conditioning, I’m thinking you need to do the HIIT stuff. The MP conditioning programs are basically HIIT stuff using movements that involve OFP and IFP. While it’s good to condition O/IFP if you can, conditioning essentially is about energy systems, so get on a bike, heavy sled, or slideboard.
Hit your high heart rates for the prescribed time, recover, then repeat. The beach will really really challenge your power output compared to grass… I was recently at the beach for Christmas with family and sprinting on the beach sucks when it’s not your normal environment 🙁
I’m not in the loop regarding Triphasic.One 😛
