For the common masses, cardio has become synonymous with fat loss. “You want to lose weight? Start running!”, is by far the most common fat-loss advice you will get. As of 2019, the mainstream image is that cardio is what you do to lose fat and get “toned”. Whereas, weight training is what you do to build muscle and look “bulky”. Naturally, with such a reputation in the air, most women stay away from lifting weights and stick to the treadmill, and maybe a couple of belly exercises at best.
Designing a good workout plan that gives you optimal results is something that needs a good deal of thought. I hear ya, your local gym trainer has an impressive physique and he just recommends hitting one muscle group a day as hard as you can. It worked for him, right? Isn’t that enough? Well, not really.
