While building strength will get those arms more defined, cardio is still king when it comes to shedding the fat that’s causing your arms to wiggle. Researchers at Duke University studying 119 overweight, sedentary subjects found that those who stuck to a cardio program lost twice the weight of those who did strength training, despite the fact that the cardio group spent 47 fewer minutes exercising every week than their weight-training peers. So, if you’re ready to get that upper body toned and tight, make sure you’re making time for cardio, too.
The biggest issue most people face in terms of the appearance of their arms isn’t a lack of muscle definition, it’s excess fat, meaning that what you’re eating is as crucial for fixing the problem as the amount you’re exercising. Instead of grabbing an electrolyte drink after your workout, try adding some grapefruit juice to your routine; researchers at Vanderbilt University found that obese study subjects who sipped a half-cup serving of grapefruit juice before meals significantly reduced their weight and BMI when compared to those who drank water instead. Fortunately, when you lose fat, it disappears all over your body, so a few sips of real grapefruit juice —the fresh, no sugar added stuff— can help you ditch those batwings for good.
Well, good (bad?) news: People who have dedicated their professional lives to defying Newton's First Law (you know them as "personal trainers") don't often have the luxury of skipping a sweat session. Next time you find yourself in need of a workout but without any of the things you think you need to get one, we got them to share the best workouts and circuits and exercises you can do anyway—no gear required.
If you want to lose weight and keep it off, you know that exercise should be an essential part of your routine. But the benefits of physical activity go far beyond just physical fitness. Increasingly, more and more research is showing that working out regularly can boost other aspects of your health as well, including cognitive function and emotional well-being.
