My history: I sit at a desk for almost 8 hours a day. Then at home I watch too many movies. I live a very sedentary life style, but I'm trying to change that. I'll be 48 in June, and I need to loose between 20 to 30 lbs. I weigh around 190 lbs and I'm 5'10".
I've tried running, and I can go for about 1 minute, and my heart rate is about maxed out and I'm so out of breath, I can't go any further. I've tried jumping rope, and again, I'm good for 1 minute and I'm out of breath and have a fast HR. So I've tried riding my mountain bike. No problems going down hill (GRIN), but I have a lot of hills and they are pretty steep. By the time I get to the top I'm out of breath and my legs are burning. I take TaeKwonDo two times a week, and the warm ups kill me. They usually last for 15 to 30 minutes, and if we do a lot of jumping rope, or squat jumps, again, I get out of breath real fast, and it takes me another 15 minutes (of course we're still exercizing) to even begin to get a normal breath rate.
I've searched the web and I've not found any recommendations for people who are just getting back into working out.
Have any of you been or know anyone that's been in a similar very poor physical condition, and know a good way to slowly increase my endurance and stamina?
I've got access to a set of free weights and dumb bells, plus my mountain bike, and a kayak and 5 gate slalom course, there is also walking, maybe a little running, and of course I'll continue with TKD.
I hope I've given you enough info and expressed what I'm looking for. If you need more info, please ask.
