hi all - i've recently decided to get my act together and start using the tredmills at my apartment complex. they're your basic model with preprogrammed routines, automated incline, etc. since i've never really taken exercise seriously, i'm not sure how to approach this to my best benefit. the only thing i currently do is try not to eat right before and do some simple stretching and warm-up. i'll stretch for a few minutes, then hit the tread at low-speed for about 3-4 more minutes. some questions i have: is there a particular type of food i should eat pre/post workout? how long should i be running? i'm currently going about 30 mins at a "fast walk". is there any special footwear i should use? i'm just using some k-swiss sneakers. is there any special technique i should use when running? breathing methods, etc...[/list=1] i understand that i need to slowly build up to this and i'm okay with that. i'm not looking to run a marathon next week or anything. i suppose i'm mostly concerned about my cardio. anyway, any comments, suggestions, etc are most welcome! thanks in advance!
