The starting point

Build physical activity around your starting point and what you can repeat comfortably. A training plan can include aerobic activity, strength, and movement variety, with gradual progression. A demanding routine is not automatically a better routine, especially if it prevents recovery or aggravates pain.

Strength Training: Building Power, Muscle, and Confidence

Strength training is often considered the backbone of any fitness program. It’s not just about building muscle; it’s about preparing the body for daily challenges, whether it’s lifting heavy grocery bags, climbing stairs, or simply standing up straight with good posture. Strength training encompasses a variety of exercises, from weightlifting to bodyweight resistance training, that target different muscle groups, building endurance and power.

Put the idea in context

High-intensity interval training alternates harder efforts with easier recovery periods. It is one way to organize activity, and it may be unsuitable or unnecessary for a particular starting point or medical circumstance. The label does not establish a special metabolic advantage. Choose an appropriate level of effort and seek qualified guidance when unsure how to begin or progress.

HIIT workouts are perfect for people with busy schedules. You don’t need an hour at the gym—just 20 minutes of dedicated HIIT can be enough to make a difference. For instance, a 30-second sprint followed by 15 seconds of rest, repeated for 10 to 15 minutes, can leave you breathless but invigorated.

Strength training can seem intimidating, especially if you’re new to weights. However, with a few tips, you can start building strength safely and confidently.

Start Small: You don’t need to lift heavy weights right away. Start with manageable weights, even if it’s just your own body weight. Push-ups, squats, and lunges are excellent beginner exercises.
