I am a HUGE fan of both Field Rations and Hit The Rack! Field Rations is hands down my favorite intra workout supplement on the market right now! I add 1 scoop to my water bottle during my strength & conditioning sessions to help sustain energy and stay hydrated. I have also found Field Rations to be a perfect intraworkout supplement for my Jiu Jitsu training sessions. Field Rations not only digests well and tastes great, but has helped me have more fuel to roll hard in the paint towards the end of class. I often recommend Field Rations to the competitive grapplers I coach who are doing multiple sessions back to back.
