Gainful has a long list of supplements and health products available, but none quite as prominent as its customized protein powder. It’s specifically designed to support muscle growth and recovery, ideal for the crucial resting time after your toughest workouts. There are whey, Keto, and plant-based formulas to match your dietary needs without the added bloat like sugars and fillers. You can choose between those options anytime, but, of course, the dietician will help you find the right one. You can also pick a goal, like losing weight, gaining it, or building lean muscle.

Honestly, we’re most excited about the flavors because they sound delicious. From Sea Salt Caramel and Cinnamon Toast to Cookies and Cream and Madagascar Vanilla you can find a flavor that suits your taste buds. You pick your base, choose your goal, and then off you go. Don’t forget that 20% off coupon code exclusive to The Manual readers. Using GAINFUL20 at checkout works with any product, including the customized protein powder. Gainful also offers performance greens, customized pre-workout supplements, hydration options, bran fiber, and more.

But let’s talk about that registered dietician support. In addition to the clean, effective formulas Gainful provides, you’ll get 1:1 access to registered and proven dieticians. They offer personalized health and fitness advice to make sure you’re getting the most out of your body. They’ll help you review your nutrition and eating habits, offer personalized advice to reach whatever goal you select and recommend lifestyle improvements to get you there more effectively. It’s like having your own registered diet and health professional, on call.

Considering how difficult it can be to reach a specific health goal, like losing weight, or gaining muscle, that added guidance is worth the subscription alone. Costs largely depend on what you’re ordering, but Gainful offers a 30-day money-back guarantee and you can delay, skip, or cancel anytime with no hassle. What do you say? Is it about time to get your health and fitness on track?

Running a marathon wearing supportive running shoes is an accomplishment, and so is crossing the finish line barefoot. Running is a high-impact form of exercise, and the right running shoes can make a big difference for runners and help with injury prevention, enhancing comfort and performance and shock absorption. Running shoes are specially designed with thicker soles that act as shock absorbers.

Some interesting fitness enthusiasts have come along and changed the paradigm, and Barefoot Bobby is one of them. There’s a buzz about Bobby in the fitness world because he doesn’t just run marathons; he crosses the finish line without wearing any shoes, hence the name.
