Push ups: Chest and thighs touch the ground at the same time, pushing up to full elbow extension.

Split jerks: start in a lunge with the torso upright, and the knees forming right angles, and jump into a lunge on the other leg.

Burpees: Chest on the ground, feet off the ground. No need to make it any more complicated than this.

Get ups: Lie on the ground, and get up. Repeat. Try attempting without using one or both hands.

Dips: On a bench, chair, step, wall or bars. Drop the shoulder below the elbow, pushing up to full elbow extension.

Box jumps: On a bench, chair, step, wall or box, jump and land as silently as possible, stand tall after launching into every jump (also called opening the hip joint, after closing it in the crouch).

Air squats: toes out, back straight, sit until the hip crease dips below the knee, and stand tall. Use arms to generate momentum.

Crunches: Put the soles of the feet together, allowing the legs to fall open, and reach down to touch the heels. Use arms to generate momentum.

Handstand push ups: Against a wall, or with assistance, nose to floor, pushing up to full elbow extension.
