If you are starting with a spotter, they should put one hand on your back, and one hand under the thigh of your kicking leg.
Keep your abdominal muscles tight so that you can keep control of your core as you bend backwards. Make sure to balance your weight firmly on the one leg that is on the ground. Do not bend you knees or elbows just yet.
In a split handstand position, your legs should be held in a perfect horizontal line above the rest of your body.
Bend the knee that lands first, resulting in a lunge position when you finish your back walkover. To keep proper form, finish with your arms straight above you and your fingers pointed upwards.
Doing back walkovers without adequate flexibility can cause injury over time.
Try doing a back walkover at the beginning of your workout to avoid the stress of thinking about it during other exercises. Recognize that psychological blocking is not a personal flaw and avoid self-blame.
