If you like shopping, do 2 laps of the largest shopping centre in Doha 2-3 times per week. Carry your groceries instead of using a trolly (if you don't have too many). Without realising it you've had a cardio and weights work out. When we arrive in Doha at the end of next month it'll be one of the first things I start doing (its my excuse to check out all the shopping centres for my new home as well!!). Good luck, maybe when I get there we can see if anyone else wants to get some walking in and meet at a shopping centre a few times a week. When you walk with someone the work doesn't seem half as hard! Good luck!!
