Jogging REALLY isn’t the way to go to change body composition for a guy your size. You say you used to lift big and all, so you’ve probably got a good bit of lean mass in there. Those people who told you your lean mass will help you keep fat off were right - though you have to clean up your diet too. Instead of “eat big” they should have said “eat big and clean.” What does your diet look like right now?
You don’t need to do long-duration “cardio” to improve heart health and lose fat. It’s actually much more efficient and safe on your joints to do higher-volume resistance training. Sled work, like the other guy mentioned, would be great. Starting with 3 or 4 50 foot pulls would be good, eventually moving up in weight and distance.
High rep squats, circuit training (not nansy pansy crap, but doing a circuit like bent over rows for 6 followed by squats for 6-8 followed by bench for 6-8 etc. for the major motions), simple high-volume training in the 10-15 rep range on a basic compound movement, complexes, all would work well. This is all assuming your heart is healthy now, of course - if not, you’ll want to take it lighter and build up volume and intensity.
I agree with orthotics if your insurace covers them. Poor foot mechanics will hold you back more than many realize. Just got a pair myself, and I feel 10x better under a heavy squat.
I would have to say my diet although I feel it is more in order than any other time in my life, could most likely use some tweaking. I am going to cut completely all carbs after 5pm and only have my carb intake in the AM and after workout. My fat intake is moderately low, without the Fish Oil and Flax Oil I take, maybe I should remove one or both of them.
I do have a sled, my daughters boyfriend welded together for me, I am just having a dificult time working out the straps part of it, currently just using a large rope and chain.
I am going to try just walking, at a normal walking pace today and see what happens, I will refrain from any jogging or quick walking motion and only use my normal pace. I will post how the shins feel afterwards. If I still have the pains, I am going to contact the Dr. and find out about those shoes someone mentioned. If today I have no pains from walking I might run up and down the bleachers to get the heart pumping.
Anyway, thanks all for the advice.
