No Room For Running

Most of us, as much as how enthusiastic waking up in the morning to run/jog to lose weight, sometimes can't have an ideal workout place. Having a place where you can do your jogging is sometimes not possible due to real world circumstances. Fortunately, there are a few exercises you can do as substitute for running.
Skip Rope - I personally do this for warm ups but this is a good cardio exercise. However, you have to develop the skill to use a skip rope first before you can totally go all the way with this exercise.
Stationary Bicycle - I recommend that you get this if you can. Aside from working out your cardiovascular endurance it also help build up your big leg muscles.
Resistance Training - Yes, resistance training can be done in a way that will give you cardio vascular benefits. You can make resistance training such as push ups and squats by just amping up the speed of execution. Doing this help increase your endurance as well as develop specific muscles you are working on
