Asalaam Walikum brothers.
I have a small issue regarding physical work out routine. Back since in high school, i used to work out on daily bases, going to public gym near my house and everything. Then when college started, i stopped going to gym because i realized it was too much fitnah there (ie. loud music and women working out there as well). SO i stopped for more then 3 years. Now for past few months, i felt like getting my physical shape back and in march i went and subscribed to gym membership. I thought id deal with fitnah with help of Allah SWT. As for loud music was concerned, i took my ipod and listened to the Quran my entire time, it was not a big deal. but women working out in very inappropriate articles of clothing (as many of you guys will know) was still a big fitnah for me. i kept my gaze down but its not 100% that your gaze will be protected by haram. So after two months of working out, i told myself i can not risk seeing haram on daily bases when i can avoid it by not going to gym and also keep my Iman protected by help of Allah SWT.
My main question for this thread is what work out can i do on daily bases at HOME, in which i can gain physical shape. I do push ups on daily bases but I know i can add many things more to my routine.
Also, I have heard muscle milk, or some products like Whey protein has haram ingredients. So what supplemental can i take for muscle milks?
ps. Some may say running is the best exercise but when its 30 deg F outside, its not possible :x.
Jazakallah Khair for all the responses.
