Switch up exercise?

So I am not big on running and what not and time is at the premium for me. Typically I ride a stationary bike for about 30 min so I can burn off close to 500 calories. But my thinking was will I continue to burn those calories if I do the bike everyday? And if I would. change it up what "quick" exercise would burn similar calories? Any ideas would be helpful.

As you improve your physical condition and your body adapts to the exercise, you will burn less calories because your body becomes more efficient at it. That's where progression comes in - ride at a higher resistance than you've been riding at and your body will again have to adapt/improve. Progression is a principle in any exercise regimen - as your body adapts to the load, you increase the load in some way (more resistance, more time/distance, etc.) to force the body to adapt again. You can change exercises if you want to, but there's no need to do so.

Other similar cardio exercises would be the treadmill, an elliptical trainer, HIIT workouts, etc. If you don't like running, you could do HIIT workouts on the bike - warm up, then sprint hard 30 seconds, rest 60 seconds, sprint 30 seconds, rest 60 seconds, etc. As your body adapts, change the intensity of your sprints and/or the interval lengths (sprint 30 seconds, rest 30 seconds, sprint 30 seconds, rest 15 seconds, etc.) to introduce progression.

...Also try to do some weight lifting! It took me a while to understand.this: If you build muscle with weights, you may not burn as much DURING the exercise but you will build muscle. Muscle requires more ongoing energy to exist than fat, so you will effectively burn MORE throughout normal daily activities if you increase your muscle mass. Hope I understood and explained that right, if I didn't i expect someone will correct or clarify for you!

It's *very* difficult to build muscle while in a caloric deficit, but weight training is highly beneficial anyway. When you lose weight, you lose both fat and lean body mass (i.e., muscle). Weight training and adequate protein intake will help preserve your lean body mass so more of your weight loss comes from fat. It also has other benefits such as maintaining bone density, strengthening both the muscles and connective tissue, etc.

If I were given the choice of doing ONLY cardio or ONLY weight training, I'd choose weight training every time. Better yet is a mixture of both - but the cardio primarily for the cardiovascular health benefits, not the weight loss benefits.
