Expect the unexpected this week.

It’s hard to know exactly where to start when you’re new to strength training. What exercises should I do? How long should I work out for? Should I exercise every day?

“Starting a new fitness routine can feel overwhelming,” says Rachel Vaziralli, CPT, director of fitness design at Orangetheory Fitness. “But remember that everyone starts somewhere, and the most important step is the first one.”

You don’t need much time to fit in an effective strength workout, nor do you need to train every day. Take things slow and increase your training as you feel comfortable.

“If you’re new to exercise, begin with two or three weekly sessions. This helps build consistency without overwhelming your schedule or body,” Vaziralli says. She points out that a good workout is about quality over quantity saying, “Ensure you perform exercises correctly to avoid injury and maximize effectiveness.”

Strength training is important because it helps to build and maintain lean muscle mass (which is even more important as we age), helps improve balance and mobility, increase bone density, and boost heart health. Ultimately, strength training helps us to complete everyday tasks with ease—and continue to do so into our later years.

Remember to talk to your doctor before implementing a new fitness routine, and be sure to be tuned into your body.

“Paying attention to how your body responds during and after workouts is crucial. Feeling sore after a new activity can be expected, but pain is not. Adjust your exercise intensity and duration to ensure you are challenging yourself without risking injury,” Vaziralli says.
