Tired of endless diets, workouts, and weight-loss programs that leave you feeling stuck? The STRONG System, created by fitness expert Cori Lefkowith, is your key to breaking free and achieving lasting results.

Cori teaches that achieving your goals isn't just about finding the right workout or diet; it is also about cultivating mental strength, self-awareness, and sustainable habits. The STRONG System empowers you to adopt a mindset that drives lasting change, moving beyond quick fixes and temporary results. STRONG stands for Significant, Targeted, Repeatable, Optimized, Nonnegotiable, GO!, and this foolproof system is everything you need to create a true lifestyle shift.

· Sustainable Habits: Build routines that support lasting progress for the long haul.
· Reflection and Growth: Learn from past experiences and use them to fuel your journey to your best self.
What makes The STRONG System unique?
· Customizable Approach: It's not about pushing a specific diet or workout. Cori's system is about understanding your needs and developing a plan that works for you.
· Age-Defying Philosophy: There is no age limit on achieving your best body. The STRONG System embraces evolving smart training and diet practices that adapt with you, free from age or performance restrictions.
· Self-Understanding: It's not just about tools and tactics; it is about knowing yourself. The system works because it aligns with your mindset and individual needs.
· Reflection for Growth: The STRONG System encourages reflection on what is worked and why so you can avoid repeating mistakes and build lasting progress.
· Evolution Over Time: As your goals change, so does your plan. The STRONG System evolves with you, ensuring continued progress and long-term results.

Additional Delivery Information (and some really important bits):
UK Delivery
Orders for delivery in the UK are normally despatched by Royal Mail, using the RM 48 Tracked Service with most orders delivered to you within a few days of placing your order with us. For larger parcels, Courier and Signed For delivery services may be used. Signed Books are shipped in our specially made book mailing cartons, with the books themselves wrapped in paper to protect them. Sometimes we may ship your order in several parts, particularly if you have 'Pre-Order' titles in your order or titles which are held in stock with our publishing partners.
The Really Important Bit: Because we use tracked, courier and signed for delivery services, please use an address at which your parcel can be received during the normal working day, for example, you may want to have your order delivered to your work address if you're not at home during the day.
First Item @ £3.75 (sometimes a shipping supplement may be added for particularly heavy books or specific postcodes*)
2 Items & over @ £5.00 in total
Another Really Important Bit: There are a number of Postcodes in the UK for which we will need to charge a shipping supplement, this will be calculated once we know the size and weight of the shipment. For these orders we will contact customers to agree a suitable and economic method of shipping. There may also be additional time required for delivery to some areas of the United Kingdom. Where possible, we will ship book orders (under 2kg) by Royal Mail to all UK postcodes. Large multiple book orders and books over 2kg are often shipped via APC Overnight or similar, regardless of Postcode.

We use the same packaging materials for our overseas deliveries as we do those in the UK. In some cases, particularly large and heavy books, or books being shipped to remote areas, may incur an additional shipping charge - if this is the case with your order, we'll notify you as quickly as possible of these charges and to arrange the additional payment. You can of course cancel your order with an immediate refund should you not wish to accept these additional costs. Shipments to overseas territories may incur additional Duty & Tax costs which could be requested by Fed Ex at the time of delivery.
