Interval training involves alternating between short high-intensity and long low-intensity activities to make your workouts more effective. When you develop your workout routine, look for activities that push your limits and are difficult to complete and plan to do them in 30-second bursts. Then choose less strenuous activities and complete them for 3-4 minutes at a time. For example, you may incorporate 30 seconds of jogging or sprinting followed by 3-4 minutes of brisk walking. Continue alternating between them until you finish your workout. Aim to exercise at least 4-5 days each week with interval training. Interval training also allows you to burn more calories than a regular workout. Doing frequent cardio workouts prevents you from getting winded during a fight and boosts how long you last against your opponent. Incorporate exercises such as running, swimming, or cycling into your weekly routine so you can stay fit. Start with a 10-minute warmup so you can prepare for the rest of your workout before switching to higher-intensity exercise to keep your heart rate in your target range. Aim to do cardio for 45-60 minutes at least 2-3 times per week. If you're at a gym or have the equipment, you can also include using a treadmill, elliptical, rowing machine, or stepping machine for your cardio workout. Strengthening your arms allows you to throw more powerful punches and block hits better. Keep your arms straight down at your sides and hold dumbbells in each hand. Make sure the weight of the dumbbells is easy for you to lift repeatedly without getting tired. Bend your arms at the elbow to curl the weights up to your shoulders in controlled motions. Slowly lower your arms back down to your sides to complete the rep. Aim to do 3 sets of 15-20 reps for your workout. Stand up straight with your arms at your side and take a large step forward with one foot. As you step forward, bend your knees until your front leg forms a 90-degree angle. Pause for 1 count before standing upright again. Alternate which leg you use after each lunge to get a balanced workout. Do 2-3 sets of 10-15 lunges. You can choose to do lunges with your bodyweight or you can hold dumbbells to make them more difficult. Lay in a plank position on the floor and plant your palms are slightly wider than your shoulders. Straighten your arms to raise yourself off the ground so your back stays straight. Lower yourself slowly toward the ground until your elbows form a 90-degree angle and hold the position for 1 count. Straighten your arms again to raise your body in a slow, controlled motion. Aim to do 2-3 sets of 15-20 push-ups for your workout. If standard push-ups are too hard, put your knees on the ground to make them easier. If you want to make your push-ups more difficult, move your body in a circular motion as you lower yourself to the ground to activate your core even more. Stand so your back is straight and your feet are slightly wider than shoulder-width apart. Bend your knees until they form a 90-degree angle to lower your body closer to the ground while you keep your back straight. Hold the position for 1 count before straightening your legs to jump off the ground. As soon as you land, start going into your next squat. Do 2-3 sets of 15-20 jump squats to get a good leg workout. Building up your leg strength allows you to move more quickly and throw more powerful kicks. Squat using 1 leg at a time if you want to make them more difficult. You can choose to do bodyweight squats or hold dumbbells if you want to increase the weight. Stand with your feet shoulder-width apart and your arms at your side. Keep your back straight as you bend your knees until they're at a 90-degree angle. Plant your palms on the ground in front of you and move your feet behind you to get into a plank position. Lower your body until your elbows are at a 90-degree angle before jumping back up into a squat. Jump in the air to straighten your legs and start your next squat immediately when you land. Aim to do 2-3 sets of 10-15 burpees. Hold your body up on parallel bars so your arms are fully extended and your feet are off the ground. Bend your elbows until they're at a 90-degree angle to lower your body and activate your chest, back, and tricep muscles. Hold the pose for 1 count before lifting yourself back up again. Try doing 2-3 sets of 10-15 reps when you do dips. Wear a weighted belt or ankle weights if you want to make the exercise more difficult. If you don't have access to parallel bars, you can also do dips using a bench instead.
