How can I make this program return a result?

Question

I have been working on this program.

One of the requirements were the following: Write a program that is split in to methods at least one of which returns a result

It don't have any errors but I need to make it return a result in order for it to work properly. More specifically to add a method that returns a result.

All you do it make the method to return something like the age

        public static void CalculateAge() {
     
            int age;
            int heartRate;
            int stretch;

            Scanner input = new Scanner(System.in);

            System.out.print("What is your age? "); 

            age = input.nextInt();
     
            System.out.print("What is your heart rate? "); 

            heartRate = input.nextInt();

            age = heart(age, heartRate);
            
            System.out.print("How far can you stretch? "); 

            stretch = input.nextInt();
     
            age = stretch(age, stretch);

            System.out.println("Your body's age is " + age);

        }  //END of CalculateAge
        public static int heart(int age, int heartRate) {
            if (heartRate <= 62) {
                age -= 5;          // block of code to be executed if condition1 is true
            } else if (62 <= heartRate && heartRate <= 64) {
                age--;            // block of code to be executed if the condition1 is false and condition2 is
                                  // true
            } else if (65 <= heartRate && heartRate <= 70) {
                age++;           // block of code to be executed if the condition1 and condition2 are false and 
                                 // condition3 is true
            } else {
                age += 2;       // block of code to be executed if the condition1 and condition2 and condition3
                                // are false and condition4 is true
            }
            return age;

        }
        public static int stretch(int age, int stretch) {
            if (stretch <= 20) {
                age += 4;      // block of code to be executed if condition1 is true
            } else if (20 <= stretch && stretch <= 32) {
                age++;         // block of code to be executed if the condition1 is false and condition2 is
                               // true
            } else if (33 <= stretch && stretch <= 37) {
                age = age + 0; // block of code to be executed if the condition1 and condition2 are false and
                               // condition3 is true
            } else {
                age = age + 3; // block of code to be executed if the condition1 and condition2 and condition3
                               // are false and condition4 is true
            }
            return age;
        }

So all I did was split the heartRate calculation into a method and also the stretch calculation into a method and out them together.
