Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie on your back, knees bent, feet flat. Arms at sides for stability. Lift hips, forming a straight line from shoulders to knees, engaging your core and glutes. Extend legs, keeping hips elevated. Pause at full extension, then return to start. Repeat with control.
Maintain core engagement to protect your lower back. Keep hips elevated throughout. Perform slowly for maximum muscle engagement. Use sliders if needed. Focus on squeezing glutes and hamstrings during the return.
