60-second boosters

Low in energy? You can get back on track in just 60 seconds by doing just one of these reviving exercises.

Spinal stretch
From a standing position, exhale as you lean forward and curl into yourself. Then, as you breathe in, uncurl and reach up to the sky with your arms. Exhale and curl into yourself again before returning to a standing position.

Energy shake
Stand with your arms by your sides. Shimmy, stretch, then shimmy again.

Abdominal breathing
When you're stressed your breathing becomes shallow, depriving your body of oxygen. Place your hands on your lower abdomen. Breathe in deeply, so the inhalation pushes your hands out. Exhale, and repeat a few times.
