Biceps flex the elbow.
Quadriceps extend the knee.
Hamstrings flex the knee.
Deltoids abduct the humerus.
Gluteus maximus extends the femur.
Gastrocnemius flexes the knee and plantar flexes the ankle.
Abdominal obliques flex and rotate the trunk.
Pectoralis major adducts the humerus.
Trapezius does many actions, mostly adduct and upwardly rotates scapula.

The atissimus obrsi abdominals is the prime mover in a sit up.
Major muscles used are: Trapezius, biceps, hip, hamstring, quadriceps, triceps, and the calf. Support muscles: Anterior and posterior deltoids, pectorals, abdominals, latissimus dorsi, and gluteus maximus.
Either he thinks you might be cold, or he 's trying to impress you with his pectorals and abdominals.
The muscles that are used on and elliptical are the pectorals, triceps, and biceps when pushing or maneuvering the handles and your gluteus maximus, hamstrings, and quadriceps when moving your legs in the stair like motion that is associated with the elliptical movements.
There are 11 major muscle groups. Triceps Biceps Deltoids Trapezius Gluteals Gastrocnemius Quadriceps Hamstrings Latissimus Dorsi Abdominals Pectorals
On each side of the anterior of the thorax you have a superficial pectoralis major and a slightly deeper pectoralis minor. There are also the muscles between the ribs called the intercostals, (external, internal and innermost)

Force summation is the combining of the correct timing and sequencing of large muscles to smaller ones will result in a good throw. For example, like in a shot put throw, the larger muscles (quadriceps) are required to flex the knee, then the energy is moved through to the gluts to extend the leg. Before energy is lost from a muscle group, the next largest comes, creating max force. The energy is then moved to the abdominals, the pectorals, then finally the biceps to give the shot put a forceful throw.
