[05:49] Karena responds to listener Brooke

Karena breaks down why earlier TIU videos used lighter weights and how her own lifting has evolved since then.

"Heavy" looks different for everyone. Whether you're excited about your first 10-pound dumbbells or pressing 25s, your capacity is valid and worth celebrating.

At 45, Karena is focused on muscle maintenance — curling at 15, rowing at 25, pressing at 15 — because after 40 we lose 1–2% of muscle mass per year.

[08:45] Karena on the full picture of fitness

Lifting heavy is only part of the equation. Mobility in your hips and joints is just as critical, especially as we get older together.

Karena's honest reminder: she used to love triathlons. Running, biking, and swimming just aren't right for her anymore. Your fitness is allowed to evolve.

Do what feeds your body and your mind. You'll know the feeling.
