A Removable Storage system provides two classes of media pools: system and application. System media pools include free media pools, unrecognized media pools, and import media pools. Removable Storage creates one free, one unrecognized, and one import media pool for each media type in your Removable Storage system.
TIP: keep an extra pair in your pack in case your feet (or your buddy's!) get wet, and on a longer hike change your socks at the top - you will be much more comfortable on the way down. Poly or silk sock liners are also a great treat on those longer hikes to help prevent friction burns (aka blisters!).
This Fitness Blender 1000 Rep Workout is a great example of a routine that boosts both your muscle content and your endurance. Other good things to look out for in hiking workouts are ones built with exercises to build lower body and core strength, especially.
