Hi all! First time poster here. Maybe some of you can help me out on this one...

Im training for a half marathon in mid-May. Ive been seriously considering taking up the P90X program but I'd like to know how possible (if minor adjustments are made)it is to do both at the same time. If so, what adjustments would be necessary to make this work??

Statistics that may be helpful:
20 yrs old
Sufficiently fit
Athletic Background
Flexible daily schedule (plenty of time to workout)

if anymore info is needed just make a note of it and I'll reply asap.
Thanks everyone!

Do both. The body is designed for work.
