You should have "warm" muscles whenever you stretch. Its good to do a light warm up lift or jog for 15-20 min stretch then lift then stretch. I will stretch between lifts if I am particularly tight in a given area. Stretching cold muscles is not as effective.
Jordan he said he does not do anything prior to lifting so cold stretching is better than nothing
15-20 minute warm up jog LOL that is over kill IMHO... I am 5'11 for about 3 years I was drinking beer/alcohol most days especially on the weekend, eating quite poor never fast food but lots of pizza and pastas. I got all the way up to 245 lbs, I HATE gyms and lifting weights. 3-5 times a week I would walk the track for roughly 5-7 minutes go through my stretch routine then I would jog/walk 2 miles it was a lot of walking when I first started out but I just kept pushing myself jogging a little more each day. I also changed the way I ate 100%... I never used to eat breakfast now I do. I'll give you my diet I am now down to 165.0 LBS as of this morning. You do not need to run stupid amounts as running is rather hard on your body and can cause serious problems as well.
I lost 80 lbs in roughly 9 months following this diet (friend and I put it together) BTW I never ever lifted a single weight or did a single push up just light jogging and ate very healty
Breakfast - 1. Fat free organic yogurt, organic blueberries, and organic plain granola.
2. Egg whites with ketchup(I use the 1g of surgar per serving stuff) you can also go egg whites and fat free cheese. Or egg whites with sea salt and pepper.
3. Cheerios (Multigrain) with fat free organic milk I eat about a cup a morning
Mid morning snack - 1. I go with a 100% Whey protein shack every single morning
Lunch - 1. I eat about .4-.7 of a lb of low sodium turkey
2. Salmon fillet or Halibut grilled with lemon and or garlic
3. My special recipe Chicken which consists of a boneless, skinless chicken breast fillet marinated in Extra Virgin Olive Oil, a lot of fresh squeezed lemon juice, fresh garlic, sea salt, fresh cracked black pepper I let it sit overnight then wrap them in foil and BBQ for 15-20 minutes EXTREMELY juicy and flavorful
4. The one and only sandwich I will eat and never feel guilty about is Turkey on whole wheat sliced bread, lettuce, onion, tomato, pickles, pepperoncinis, oil and vinegar, and yellow mustard. DO NOT have mayo or cheese.
Snack - 1. You can go with lots of options I like fresh watermelon, apple, or egg whites, fat free cottage cheese is also an option.
2. If you can find a really healthy tortilla chip with sea salt and organic you can eat them with any fresh salsa.
Dinner - 1. I do a lot of the same stuff for dinner my "special" chicken, salmon, halibut, I will also do Chicken Fajitas my local Upscale market has premixed chicken fajita mix. You can find some organic "healthy" tortillas you can have fat free sour cream, i would say no cheese as it is very high in calories (I love cheese it was hard for me at first)
Salads at first go with EVOO and vinegar with mixed greens some cucumbers, fresh tomatoes stay far away from real salad dressings for awhile ie no ranch, blue cheese, Caesar, or thousand island. Lemon juice is also an option
Waldon Farms is a brand that sells really healthy diet dressings... they also have BBQ sauce, maple syrup and others
