The exercise “Cross Lunge” is ideal for well-defined legs and a sexy, well-toned butt. Here’s everything you need to know, in a nutshell:

Who? For mother with baby, or also solo
Where? Indoors or outdoors
How often? Depending on your fitness level: start with 8-10 repetitions per side (alternating), followed by a short break; then do another 8-10 reps
Info for the mother: Concentrate on keeping your stomach and pelvic-floor muscles tightened during the exercise; keep your breathing even and calm

The exercise

Starting position:

• Stand behind the Croozer
• Move the tip of your right foot to the side
• One or both of your hands are resting on the handlebar
• Keep your stomach and pelvic-floor muscles tight

The movement:

• Step with your right foot back and to the left
• Only the toes should touch the ground; keep your heel raised
• Bend both knees and push your hips backward while descending into a lunge position
• Straighten both legs and return your foot to the starting position
• Do several repetitions, alternating sides

An important reminder:

• Maintain the tension in your stomach and pelvic-floor muscles
• Keep your back straight for the entire exercise
• When doing the lunge: your front knee should be aligned with your foot and directly over your ankle, keeping your weight on the heel
