Frog Rock Back | Self-stretch in 3D
Frog Rock Back: all fours, inner thighs and hips. Preparation, 4 movement phases, points to check and cautions, with a 3D model you can pause and rotate.

Position and focus
All fours · Inner thighs and hips
A dynamic stretch for the inner thighs and hips, moving through a gradually larger range. It can also be used to prepare before exercise.
Starting position
From all fours, open the knees wider than the hips and place the ankles in line with the knees.
Movement phases
1. Set up
Place the hands under the shoulders and flatten the back.
2. Small rocks
Rock the hips back towards the heels and forwards again.
3. Larger rocks
Within a stretch in the inner thighs, rock further back.
4. Smaller and stop
Make the movement smaller, bring the knees together and stop.
What to check yourself
Check that the knees are comfortable and the back does not round too much.
Caution
Stop if you feel sharp pain, numbness, dizziness, shortness of breath or anxiety. If you are receiving treatment, recovering from surgery or pregnant, check with your healthcare professional first.
