Two things are essential for a proper exercise regimen: cardio & strength training. Don’t listen to anyone who says you don’t need one or the other.
When it comes to cardio, think of your heart like a car engine. The speedometer shows you how fast you're going, but the tachometer shows how hard the engine is working, regardless of speed. Your heart operates on the same principle, where your heart rate is the tachometer. If you haven't been active lately, your heart rate will increase even if you're not moving fast. The more you train in different heart rate zones, the more efficient your heart becomes & allows you to do more work with less effort.
Athletes target one of five zones ranging from very light to maximum heart rate. But for the average person, you can really bucket them into three: low aerobic, high aerobic & anaerobic. Using a heart rate monitor will tell you how much time you've spent in each zone.
Low aerobic/base (zone 1 & 2) is generally easy. You can breathe easily & hold a conversation. It involves little to no fatigue. This zone builds endurance & supports recovery.
High aerobic (zone 3 & 4) includes moderate activity. Talking becomes a bit more difficult & heavy breathing begins. This zone benefits cardiovascular health, significant calorie burn, & higher fat burn during exercise.
Anaerobic (zone 5) is a very hard effort. Breathing is labored & you can't talk. This zone benefits calorie burn both during & after exercise, increased tolerance for high intensity exercise & prolonged time to fatigue.
High aerobic & anaerobic have a direct impact on cardiovascular health & calorie & fat burn. Getting into anaerobic specifically has what's called an afterburn effect or EPOC - Excess Post-exercise Oxygen Consumption. This means that your body continues to burn calories even after you've stopped exercising because it requires extra energy and oxygen to repair muscle damage, replenish fuel stores and restore hormonal balance and can lead to greater weight loss.
I cover this in more detail in my 6-week group wellness program.
