+# 23 4_Fitness
+
+
+## Task @showdialog
+Create a fitness program! Define 5 colors and assign a fitness exercise to each color - for example, squats, stretch jumps, jumping jacks, etc.
+Observe the following guidelines for your fitness program:
+- 10 exercises
+- 3x jumping jacks in a row
+- 2x squats
+- Finish with a stretch jump
+
+## Define exercises
+Insert a ``||basic.set LED to||`` and ``||basic.pause||`` block for each of the 10 exercises.
+
+## Repetitions
+Optimize your program by recognizing repetitions and using repetition loops instead of mapping the same command several times in a row.
+Use the ``||loops.repeat x times|||`` block and set the desired repetition.
+
+## Optimize repetitions
+If a color is repeated, you need a visible pause between the phases.
+Use the ``||basic.turn built-in LED off||`` block to switch off the RGB LED.
+You can find it under ``||basic.basics||`` ``||basic....more||``.
+Add a ``||basic.pause||`` block to define the duration of the pause.
+Complete your program.
+
+## Use variables @showdialog
+Use a variable to define the speed of your animation and adjust it easily.
+
+## Create variable Tempo
+Create a ``||variables.variable||`` and name it "Tempo".
+
+```
