That’s why building muscle mass before and while you age is key to longevity.

Megan Roup,who trainsDakota Johnsonand founder of digital platformThe Sculpt Society,suggests starting with one specific group.

Core strength as you age can help you continue to stay active, she says.

Women over 50 should concentrate on maintaining activity levels and muscle, Roup says.

Tap your right foot on the floor and bring it back up to hip height.

Repeat 12 times and then do the exact same on the left side.

Keep core engaged the entire time as you breathe through the exercise.

Plank

I love a plank because it is full body and we are hitting multiple muscle groups!

Bring your hands under your shoulders and walk your feet back into a plank.

If this is too difficult you’ve got the option to bring your knees down to the floor.

As your breath in your plank, the core remains engaged.

Your transverse abdominals (corset muscles) continue to wrap center.

Bring your right knee into your chest and step back for 8 reps. Repeat the left side.

Knees are stacked and bent side.

I love a side plank to strengthen your obliques and deep core.

Advanced clients can fully extend legs side.

Do 8 to 12 reps on right side then repeat left side.
