I'm training for a Rainier climb late this summer and am curious about what others find to be the best exercises for strength training and conditioning.
I know that the best way to get in shape for climbing and backpacking is to do just that, hike, climb, and so on with a heavy pack.
However, beyond that, if you had an extra 20-30 minutes at least twice a week to devote to specific strength training what would you choose to do? I've had and consulted the book Conditioning for Outdoor Fitness (published by The Mountaineers) for years, so I'm not starting from scratch.
I've got a regimen that includes: squats, lunges, abs, push-ups, calf raises, but am curious if anyone has other suggestions: plyometrics, etc... I want to make the little extra time I do have worth my while.
