Strengthen your core

1 Front plank

What to do

Technique
Assume the press-up position, but supporting your weight on your forearms and the balls of your feet. Tense your glutes and keep your trunk straight. To begin, do multiple sets for a short period of time (10 to 20 seconds), and then gradually do fewer sets for a longer time. Breath normally – don’t hold it.
