In the world of fitness, superstitions and myths vie with fact to stymie good intentions.
While certain misapprehensions have been disavowed, like the notion that weights make you bulky, others remain.
Most people believe that when lifting weights, you should keep your chest up, your shoulders back and the back arched. This might look like good posture, but it locks up the spine, constrains shoulder mobility, and strains the back. Your upper body will be tense, the muscles tight, and your breathing shallow. It all spells stress. Instead, keep your ribcage down, like after you sigh enthusiastically, for the best results.
Although many fitness instructors have been taught that high reps are better for endurance while low reps are better for strength, it’s not true. Lower reps in fact improve both strength and endurance. Focus on eight or fewer reps to start so you get strong first, and then increase reps.
We’ve all heard that weights are for muscle and cardio burns fat. But in fact, lifting weights will improve your body’s appearance no matter what your goal. The key to weight loss is diet, not cardio. Eat fewer calories than you burn and you will lose weight. Cardio and weights are not mutually exclusive.
And now we come to carbs – the nemesis of dieters. We all need some carbs. The body turns them into glucose to use as fuel. While you can get some carbs from vegetables and fruit, whole grains, rice and potatoes are easier sources for active people. Cutting carbs may help you lose weight in the short term, but it is likely to be mostly water.
