The Spartan is a fun opportunity to embrace the power of obstacles making us stronger. OMMS!
Training-wise, there are three areas to focus on:
1. Grip strength, both as an absolute and relative to weight.
2. Off-terrain hiking and aerobic conditioning.
3. Specific Spartan skills.
For each skill, consider both getting very specific and focusing on incremental improvements.
Want to learn how to climb a rope? Research how to do it. Find a gym with a rope and practice climbing.
And also, burpees. 😄
