How to Grill Flank Steak. Flank steak is a flavorful cut of meat taken from the flank (lower abdominal region) of the cow. In the hands of a budget-minded cook, flank steak can be a delicious yet affordable alternative to pricier cuts of beef like prime rib and other steak varieties (T-bone, ribeye, etc.).
Although riding a stationary bike is predominantly a lower-body and cardiovascular exercise, your upper-body muscles get in on the act too. As you lean forward on the handlebars, your triceps, deltoids and pectoralis major muscles must work to support your weight.
The core muscles also power your turns and help you control the bike. While the cycling position does strengthen your core muscles, additional core exercises will increase your core's endurance and power, leading to improvements during your rides. The glute bridge, front plank and mountain climbers are examples of exercises that strengthen the core muscles.
