Benefits and Disadvantages of Multi-Joint Exercises




Joint exercises are an excellent way to get your entire body physically fit and fully functional. Multi-joint exercises, also known as complex exercises, are one form of these exercises. Some of the multi-joint movements that you can perform include step-ups, lunges, leg presses, dead lifts, push-ups and squats. Step-ups engage the lower body muscles. Leg presses encourage increased muscle growth to the quadriceps, hamstrings, calves and glutes due to the heavier resistance involved. Dead lifts increase muscular mass in both the lower and upper body. Push-ups increase muscular mass in the chest, shoulders, back and triceps. Squat exercises vary but generally focus on the quadriceps, hamstring, calves and glutes. They help to develop your hip and thigh muscles.

Benefits of Multi-Joint Exercises

Multi-joint movements are regarded as more beneficial to the body than isolation exercises. This is because they engage various muscles within the body which work simultaneously to yield several benefits. You also burn more calories during multi-joint workouts than isolation exercises. This is due to an increased metabolic rate which results in more fat loss. It helps you to develop a lean, strong body. Multi-joint workouts also help to increase your resting metabolic rate (RMR) after exercise significantly. This enhances increased fat-burn and supports an effective weight loss program. The risk of injury is significantly lower during complex exercises. The simultaneous activity of various muscle groups creates a harmonious pattern that promotes safety as you workout. This decreases the risk of injuries during workouts. It also helps you to develop a fully functional and fit body.

Disadvantages of Multi-Joint Exercises

However, multi-joint movements may fail to develop a particular area of your body to the desired level. This is because certain muscles during the exercise bear more of the load than other muscles. For this reason, you may want to complement multi-joint movements with single-joint movements.

Compound Exercise #1: Squat Jump Into Lunge 
Target Muscles: Quadriceps, Hamstrings, Calves and Glutes
- Set up a barbell on a rack, then slowly lift it off of the rack and onto the back of your neck. *The barbell should be a light/moderate weight that will allow you to confidently jump up without getting injured.
- Ensure your feet are shoulder-width apart.
- Jump straight up into the air and land into a squat position.
- On completion of the squat go straight into a lunge, right leg in front of left, then lunge your left leg in front of your right. This constitutes as 1 rep.
Perform 12-15 reps x 8 sets 

Compound Exercise #2: Hanging Clean Into A Front Squat 

Target Muscles: Quadriceps, Shoulders, and Calves 
- Lift the barbell from the rack/ ground and ensure the weight isnt overloaded.
- Lower yourself into a squat and hold the bar in front of your shins with a shoulder-width, overhand grip.
- Then shrug your shoulders as you pull the bar straight up and rise onto your toes.
- As the bar approaches chest height, bend your knees and swing your elbows forward to catch the bar in your fingers.
- While keeping your elbows high, lower your body until your thighs are parallel to the floor, then push back up and lower the bar to the starting position.
Perform 12-15 reps x 8 sets

Compound Exercise #3: Deadlift Into Bicep Curl

Target Muscles: Quadriceps, Shoulders, Calves, Biceps 
- Squat down and grasp a barbell with a shoulder width or slightly narrower underhand grip.
- Standing with your feet shoulder width apart, your knees slightly bent, and your back straight, draw your abs in and  lift the bar by extending hips and knees to full extension.
- Then curl the bar by bending at the elbows, bringing your wrists to your shoulders and keeping your elbows in a locked position.
- Extend your arms and return the bar to the standing position at your thighs.
- Return to the starting position by bending at the waist and bringing the bar back down to just above the floor.
