Looking to squeeze in a quick workout on a busy Monday? When I'm in a crunch, one of my favorite timesaving tricks is to focus on exercising the big muscle groups (chest, back, butt, and legs) in my body. Working the large muscles is a fabulous way to boost your metabolism since the bigger the muscle, the more muscle fibers activated, and therefore the more calories burned.

We've heard that it
doesn't pay to be macho when lifting weights. So why do so many people — sorry to say, it's primarily men — insist on slamming down their weights? More often than not, my gym workouts are rattled by the clanging of weight plates or the sound of someone dropping a giant barbell onto the floor.

You know you should be spending time strength training, but you already spend a lot of time at the gym doing cardio and don't think you can fit in toning sessions. Don't assume you have to spend hours lifting weights — it doesn't take much to start seeing results. Start with 20 to 30 minutes of strength training sessions
twice a week.
