You need a fitness board to make a dumbbell bird, otherwise you can only do it in bed.

First of all, there should be a pair of dumbbells with adjustable weight. Different weights aim at different actions. The number of each group is 8 to 12, which is most suitable for beginners to practice muscles.

Each group should rest for no more than one minute, and each movement should rest for no more than two minutes.

Chest: dumbbell bench press 4 groups

Dumbbell flying bird 4 zu

4 groups of push-ups (20 to 30)

Practice twice a week with an interval of more than 48 hours.
