I live in an extremely polluted city in China and therefore need to exercise indoors. In the past I've always trained as a distance runner, but running outdoors here is just not that wise due to pollution and traffic concerns, so I would like to develop a fitness routine I can do indoors when I can't make it to the gym. I would ideally like to combine strength training and cardio and use no or minimal equipment. also since I'm not running much anymore I'd prefer to build some bulk rather than stay lean like I usually am. Tall order I know but any routine suggestions would be greatly appreciated! Cheers

Thats a really good question
my advice would be sit ups, crunches, pushups,lunges , mabey try buying an excercise ball (the big ones try 75 cm) and download a workout routine for that. remember to stretch before and after working out…
hope this has been a help
