How to do the Frog Sit-up
Lie with your back flat on the floor (or exercise mat) and your legs extended in front of you.
Now bend at the knees and place your outer thighs by the floor (or mat) as you make the soles of your feet touch each other.
Now try pushing both soles and bringing them up as near you as possible while you keep the outer thighs on the floor (or at least almost touching it). Tip: In this position your legs should create a diamond shape.
Now, cross your arms in front of you by touching the opposite shoulders. This will be your starting position.
As you exhale flatten your lower back to the floor while curling the torso upwards. Tip: This will be like performing the first 1/4 movement of a sit up. Hold at the top position for a second.
As you inhale, slowly lower back to the starting position.
Repeat for the recommended amount of repetitions.
Sets and reps
| Goal | Sets | Reps | Rest |
|---|---|---|---|
| Muscle growth | 2–4 | 10–15 | 1 min |
| Muscular endurance | 2–3 | 15–25 | 45 s |
When you hit the top of the rep range on every set, add a rep or a harder variation next session.
Starting points from training research. Stop each set 1–3 reps short of failure.
Muscles worked
Primary
The abs flex your spine and stop it from arching. Mix crunching moves (crunches, leg raises) with anti-extension work (planks, rollouts).

- 2 day workout plan: build muscle training twice a weekA 2 day workout plan that still builds muscle and strength: two full-body sessions, sets and reps, supersets to save time and what results to expect.
- 30 minute gym workout: templates that build muscleA 30 minute gym workout can build real muscle. Supersets, smart exercise choice and three ready-to-use templates for 30 to 45 minute sessions.
- 4 day workout split: best options and a full programWhich 4 day workout split is best? Upper/lower, full body, torso/limbs and bro splits compared in brief, then a complete 4-day program with sets and reps.
