Exercise 1: Dumbbell Curls (Biceps)
As the most iconic move in the sequence, this targets your biceps. Stand tall with a dumbbell in each hand, palms facing forward. Keep your elbows close to your torso and curl the weights up toward your shoulders.
- Focus: Control the weight down; don’t let it drop.
- Reps: Aim for 10-12 per set.
Exercise 2: Goblet Squats (Legs & Glutes)
This variation is great for beginners. Hold a single dumbbell vertically close to your chest. With feet shoulder-width apart, lower your body as if sitting in a chair, keeping your chest up and knees tracking over toes.
- Focus: Go as low as your mobility allows.
- Reps: Aim for 12-15 per set.
Exercise 3: Floor Press (Chest)
If you don’t have a bench, this is a safe alternative. Lie on the floor with knees bent. Hold dumbbells above your chest with arms straight. Lower the weights until your upper arms touch the floor, then press back up.
- Focus: Keep your core engaged to protect your lower back.
- Reps: Aim for 8-10 per set.
Exercise 4: Upright Rows (Shoulders)
Shown briefly in the group shots. Stand holding dumbbells in front of your thighs. Pull the weights straight up along your body to chin level, leading with your elbows. Lower with control.
- Caution: Do not jerk the weight; use a manageable load to avoid shoulder strain.

Voice Actor Contributions And Recording
Ai Fairouz and Shizuka Ishigami have both mentioned in interviews that recording “Onegai Muscle” was a unique experience. They had to sing with the same energy their characters would have while working out.
