Instructions
Alternate Leg Diagonal Bound
Assume a comfortable stance with one foot slightly in front of the other.
Begin by pushing off with the front leg, driving the opposite knee forward and as high as possible before landing. Attempt to cover as much distance to each side with each bound.
It may help to use a line on the ground to guage distance from side to side.
Repeat the sequence with the other leg.
Leg Extensions
For this exercise you will need to use a leg extension machine. First choose your weight and sit on the machine with your legs under the pad (feet pointed forward) and the hands holding the side bars. This will be your starting position. Tip: You will need to adjust the pad so that it falls on top of your lower leg (just above your feet). Also, make sure that your legs form a 90-degree angle between the lower and upper leg. If the angle is less than 90-degrees then that means the knee is over the toes which in turn creates undue stress at the knee joint. If the machine is designed that way, either look for another machine or just make sure that when you start executing the exercise you stop going down once you hit the 90-degree angle.
Using your quadriceps, extend your legs to the maximum as you exhale. Ensure that the rest of the body remains stationary on the seat. Pause a second on the contracted position.
Slowly lower the weight back to the original position as you inhale, ensuring that you do not go past the 90-degree angle limit.
Repeat for the recommended amount of times.
Verdict
Both exercises target the quadriceps. Alternate Leg Diagonal Bound is a beginner exercise using none, while Leg Extensions is beginner and uses machine. Choose Alternate Leg Diagonal Bound if you have access to none, or Leg Extensions if you prefer machine. Alternate Leg Diagonal Bound is a compound movement working multiple joints, making it better for overall strength. Leg Extensions isolates the target muscle for focused development.
