1. She Does Planks

Silva swears by planks as a great way to work on her core. “Lunges, squats, and planks (a move that looks a bit like a push-up and is often substituted for sit-ups) are key moves in most good core workouts,” says Harvard Health. “Sit-ups and crunches—once the bread and butter of core work—have fallen out of favor in recent years. Why? They can actually cause back pain, partly by focusing only on abdominal muscles. Exercises like planks efficiently work many more core muscles at once.”

2. She Lifts Weights

Silva lifts weights as part of her workout routine. “Strength training may enhance your quality of life and improve your ability to do everyday activities,” says the Mayo Clinic. “Strength training can also protect your joints from injury. Building muscle also can contribute to better balance and may reduce your risk of falls. This can help you maintain independence as you age.”

3. Ab Workouts

Silva is all about the abs, and doesn’t shy away from intense workouts. “Strong core muscles make it easier to do many activities,” says the Mayo Clinic. “When your core muscles are strong, it's easier to swing a golf club, get a glass from the top shelf and bend down to tie your shoes. Strong core muscles help athletes, such as runners. That's because weak core muscles can lead to more fatigue, less endurance and injuries. Weak core muscles can leave you more prone to poor posture, lower back pain and muscle injuries. Strengthening your core muscles may help back pain get better and lower the risk of falls.”

4. She Uses Kettlebells

Silva likes to use kettlebells as part of her exercise routine. “The kettlebell swing is a great way to increase heart rate and burn calories,” says Chris Kolba, PT. “It’s been used often as an exercise to improve cardiovascular health and shed those unwanted pounds. The key is to do multiple sets for higher repetitions and to be consistent. While there are hundreds of ways this can be organized a few examples are: Start with 15-20 swings and add 10-20 swings each day, do 5-10 rounds of 30-50 swings, or mix them with another exercise like 30-50 swings and 10 push-ups for 10 rounds.”

5. TRX Training

Silva loves TRX resistance training exercises. “For many years, the CDC has recommended that along with aerobic activity, adults do some type of strength training twice weekly to combat muscle loss,” says Benjamin R. Snell, MD. “These sessions should include all major muscle groups—legs, hips, back, abdomen, chest, shoulders, and arms. Muscle mass decreases with age, putting you at higher risk for diabetes (skeletal muscle uses glucose), as well as falls and other injuries.”
