I've been using gymjones - the gym started by Mark Twight, the climber. Yea, I paid a subscription to get access to their website - $500 per year. But the programs are geared towards climbing, ski mountaineering, biking, etc. so are specific to an outdoor skill set and training needs.
I keep a log of the exercises so a one year subscription will do me to collect the needed data. It is much better than crossfit which, while free for the workout of the day, seems a random collection of exercises not meant to do much other than build your ability to do crossfit exercises. This spring my strength and stamina in the mountains - including a backcountry trip to Iceland, was improved on the long days.
If interested I'd recommend the month-long basic program to get used to the intensity of the workouts. And if you have no experience with Olympic-style lifting I'd get some coaching from a trainer first. Cheers.
