[Verse 1]
Be strong, be hard
Resist temptation
Stick your hand in your eye
Close your fist, resist
Walk on this line
Look straight ahead

[Refrain]
Flex your muscles
Flex your muscles
Flex your muscles
Flex your muscles
Be hard, be strong
Be hard, be hard
Hard, hard

[Verse 2]
And come back for more
Ah, come back
Ah, come back
Flex your muscles
Flex your muscles
Ah, come back

[Refrain]
Be hard, be hard
Flex your muscles
Flex your muscles
Come back
Come back
Flex your muscles
Flex your muscles
Be hard, be hard
Hard, hard
Hard, hard
Be hard, be hard
Be hard, be hard
Flex your muscles
Flex your muscles
Flex your muscles
Flex your muscles
