Diving makes you slim!

When we first started joining the diving school near our current house for courses and dive trips, we saw this slogan saying "Tauchen macht schlank", which means "Diving makes you slim".

all the carrying of heavy diving equipments and effort putting on the dive suit alone will make you feel like as if you have done a long jog or so!
