OK... I know that there are undoubtedly some posts out there that cover this and I am starting to mine them, but in the meantime I'd love to hear from people who can both relate and provide some good advice for me specifically. So, here's the deal...
I am 34-year-old male who's carrying around approximately 70 extra pounds that I want to rid myself of, the next two years. Even when I was young and fit, I was a somewhat stocky at 5'9" 180 (when I get below 180 I actually start looking a bit gaunt). Despite my imposing (and not in a muscular way) physique I do manage to do a bit of hiking in the Sequoia NP area. Usually 10-15 mile day hikes between 7,200' and 10,300' a couple of times a month during the summer. Unfortunately, I usually do take a day (or two) to recover after each hike.
In theory, if I can shed the weight, I know I have the strength to go higher and longer. For instance, last September I attempted Mt. Whitney with a couple of friends and was able to make it from portal to trail camp (approx 6.3 miles from 8,360' to 12,000') carrying a 50+ pound pack. Unfortunately, after that day, I was spent. Besides being slower than molasses (about 5.5 hours) I didn't hydrate well and didn't acclimate enough and may have ended up with a touch of altitude sickness. Sadly, the next morning while my friends summited it was all I could do to to drag my butt off the mountain. At the end of the day it's really no mystery, though, that the only thing holding me back was my own fat a**.
So, now I want to lose the weight, but I honestly struggle to know where to start. We all have gifts in life but physical prowess, training, fitness and motivation have never been my strengths. But I love hiking high and want to learn some basic climbing. Anyhow, I want to get up Whitney next time I go back and as I may be moving to Washington soon I want to climb Rainier in the next year or two, as well. So those are the two primary goals I have in mind. I NEED TO LOSE THE WEIGHT...WHERE DO I START? What are your recommendations of books, videos, training regimens should I look to in order to simultaneously lose weight and train for climbing? I'd love to hear from some of you huskier hikers/climbers out there who've had similar struggles, or anyone who can muster empathy for my plight without recommending a regimen that will kill me or sap my motivation to try.
