A little combination you can practice on the heavy bag. You could also practice with a partner, just hold back the power on the strikes.
Start with a front kick (mae geri) from the back leg. After the impact, bring the leg halfway back, maintaining control and then step in with the same foot and drive forward with a rising forearm technique (age uke). The mae geri can target the solar plexus, abdomen, hip or knee. The age uke is coming up under the chin.
You can see on my bag I like to mark the knee and solar plexus height with tape to assist targeting.
