Pedal intensely for 20 seconds Rest for 40 seconds Do this for 10 to 15 minutes It drains your muscles fast
The 20-second hard effort really gets the heart rate up without needing a long cardio session
the 40-second recovery because it gives enough time to prepare for the next hard push
Ten minutes sounds easy until you actually try to maintain those intense intervals
This looks useful when Iโm short on time and still want a challenging conditioning session
Iโd start with fewer rounds and build up once my body gets used to the intensity
Keeping the hard intervals consistent is more important than trying to go all-out every round
Good option for a quick cardio finisher, but Iโd avoid doing it too often if leg recovery is already an issue
