Yes, it’s a fitness exercise--for your Spirit. In 15 minutes daily, this common-sense study approach builds biblical fitness. Easily digestible chapters (theme based, Scripture focused) offer key points and provide 5 days of progressively challenging tasks. Weeks end with a practical application (a bit more time involved). Both Student and Core 52 (for adults/students wanting meatier challenges) cover the same 52 most important Bible concepts/passages in the same chapters. But titles, writing styles, chapter lengths, and examples are unique to the target audience. Core 52 is 369 pgs, sc. Student is 255 pgs.
