For our purposes here, high-intensity cardio falls between about 80 to 90 percent of your maximum heart rate (MHR) or, if you're not using heart rate zones, about a 6 to 8 on a 10-point perceived exertion scale. What this translates to is exercise at a level that feels challenging and leaves you too breathless to talk in complete sentences. But you're not going all out, as in sprinting as fast as you can. There's no doubt that some high-intensity training work can be helpful for weight loss as well as improving endurance and aerobic capacity.
5. Wind Markers: Mark a starting line on the round, then mark four points out in front of that line, each approximately 10 yards apart, for a total of 40 yards (an approximation is fine). Start in a sprinting position at the starting line. Sprint out as fast as you can to the first marker, then turn and sprint back to start. Repeat this out and back pattern to each line. After you’ve returned from the fourth line, perform 4 burpees, then 4 push-ups. That’s 1 round. Complete 7 rounds as fast as possible.
How to do a Turkish get-up: Holding one kettlebell by the handle with both hands, lie on your side in a fetal position. Roll onto your back and press the kettlebell up toward the ceiling with both hands until the weight is stable on one loaded side. Release your free arm and free leg to a 45-degree angle with your palm facing down. Slide the heel of the loaded side closer to your butt to firmly grip the floor.
Research also finds that drinking frequently—even if it’s a moderate amount—can set you up for excess pudge. Not only do the beverages themselves contain unnecessary calories, but once you start sipping too much, your inhibition also plummets, according to one 2016 study. The result? You’ll have a hard time resisting that late-night slice of pizza. So if you're going to imbibe, be sure to stick to one drink per day for women and up to two drinks for men.
Try this HIIT workout: After a 10-minute warm-up, spend 30 seconds doing as many reps as possible of squats, push-ups, kettlebell swings, or single-arm rows. Then, rest for 30 seconds and do a different exercise for another 30 seconds. Continue for 10 rounds. Choose any of your favorite exercises—just make sure you alternate between exercises that work different muscle groups, which will help certain muscles recover while you work others.
2. Eat smaller meals more frequently: “Insulin is probably the single most important factor that contributes to fat storage,” Seedman explains. This hormone is activated when you eat and responsible for shuttling nutrients into cells, either fat or muscle. A quick biology lesson: Every time you eat a meal, your blood glucose spikes, and when this goes up, so do your insulin levels. More calories at once means a larger spike in both. When these levels are sky high, it signals to your body to put nutrients into fat cells instead of muscle, causing an accumulation of fat, Seedman explains. The same thing happens when your insulin stays elevated for a prolonged period of time, which is why it’s important to let yourself become hungry before eating again, he adds. Aim for five to six meals throughout the day.
