The Machines
Triceps Extension
Biceps Curl
Agonists, Antagonists, and Stabilizers
Biceps Curl Exercise Machine
Target Muscles
Agonists: Brachialis, Biceps Brachii, Brachioradialis
Antagonist: Triceps
Synergists: Other flexor muscles of the fingers.
Stabilizers: Anterior Deltoid, Coracobrachialis,
Pectoralis Major, Supraspinatus, Infraspinatus.
Type of Contraction and the End Feel
• From the starting position, the muscle
contraction is concentric and is against gravity.
Returning to the starting position is gravity
assisted and slow eccentric contraction is
advised.
• The end feel of the biceps exercise is soft
because of the muscle bulk approximation
Range of Motion:
Starting ROM
90 degree Shoulder Flexion
0 degree Elbow Extension
End ROM
> 90 degree Elbow Flexion
Minimum required Strength:
Fair +
• Patients is expected to have the minimum required
strength and ROM to operate the machine properly.
• Patients who does not have the minimum required
strength should do isotonic exercises
• Patients could also do substitution exercises in gravity
eliminated position
Triceps Extension Machine
Target Muscles
Agonists: Triceps Brachii
Antagonist: Biceps Brachii, Brachialis, Brachioradialis
Synergists: Anconeus
Stabilizers: Anterior Deltoid, Coracobrachialis,
Pectoralis Major, Supraspinatus, Infraspinatus.
Type of Contraction and the End Feel
• This triceps exercise is utilizing gravity
assisted concentric muscle contractions.
To get better results, it is advised to do
slow eccentric contractions.
• End feel of the triceps exercise is hard
because of the humerus and radio-ulnar
approximation.
Range of Motion
Starting ROM
90 degree Shoulder Flexion
> 90 degree Elbow Flexion
Ending ROM
0 degree Elbow Extension
Minimum Required Strength:
Fair +
• Patients is expected to have the minimum required
strength and ROM to operate the machine properly.
• Patients who does not have the minimum required
strength should do isotonic exercises
• Patients could also do substitution exercises in gravity
eliminated position such as lying supine
Result of Improper Exercise.
If exercises are done in improper
way individual will end up obtaining
cramps and aches or in worst situation
person might be even bed ridden.
Also, if the weight of the machine or a
substitute dumbbell is heavier than
the person's capacity, he will
overstretch his muscles and end up
with strain and sprain of the muscles
and tendons.
Contraindications for Triceps and Biceps Machine
Use
• Inflammation of the muscles, tendons, and
ligaments
• Inflammation of the joints in the shoulders and
elbows
• Fractures and Dislocations
• Pain
