Circuit training is invaluable when done well, not only does it take less time which many people have very little of but you not gain strength and also a CV benefit from this style of training. As well, it may more accurately mimic what your body is going through when climbing demanding terrain.
How to build a circuit: this can seem challenging and often is so once again I will keep it simple to begin:
Four to five exercises combining these critical components:
- Squat: (ex) squats, dead lifting, lunging, step-ups, box jumps, side lunging
- Sit: (Core) sit ups, back extension, rotational strength, leg raises, med ball throws, and balance
- Push: Push-ups, dips, over head press, bench press
- Pull: pull ups, high pulls, cable rows, bent over row
- Metabolic (optional): rowing machine, running intervals, jumping rope
These are all the functional Ranges of Motion that our bodies can and do work in. We have to train them all and in harmony with one another. You will rapidly discover that a weakness in one area will diminish your capacity to perform specific movements. We want to train away those weaknesses. Those weaknesses are what will lead to inability to perform any complex endeavor such as ice climbing, skiing, and biking, at your absolute best.
