The most recent M1 model holds 490 gallons (1,850 L), allowing the tank to go about 265 miles (426 km) without refueling. The turbine engine works with a range of fuels, including ordinary gasoline, diesel fuel and jet fuel.
Lunging Forward. The lunge is a great movement for developing the thighs and strengthening the hips. Lunges target two primary muscles groups: 1) the hip extensors, comprising the gluteal muscles (glutes) and hamstrings. 2) the knee extensors, made up of the four muscles collectively known as the quadriceps.
A rear lunge works the same muscles but with more emphasis on the quadriceps. The secondary target area is glutes in the buttocks and the muscles in the front and rear of the calf. You do a rear lunge much like a forward lunge, except you step to the rear rather than front. You bend the forward leg until the thigh is parallel to the floor, and bend the rear leg until the knee almost touches.
