Learning Objective: Introduction to antagonist muscles and how to effectively train them to prevent injury
Three types of muscle contraction
Understanding - Agonist / Antagonist Muscle
Why antagonist training is essential
Antagonist muscle(s) training
Tibialis Anterior

Duration: 15-20 mins
Equipment: Just need to find a space and preferably a yoga mat / carpet
The muscle shortens to create movement. Example: Curling a weight into a bicep curl.
The muscle lengthens to control movement. Example: Slowly letting down a weight from a biceps curl.
The muscle sustains a fixed position to stabilise movement. Example: Holding a weight in the mid range of a biceps curl.
Let's use the example of a bicep curl as above,
Bicep (AGONIST) contracts and undergoes a concentric muscle action
Tricep (ANTAGONIST) on the opposite side of the arm lengthens and relaxes to allow the elbow to bend. The triceps antagonises or opposes the movement of the curl
Role-reverse when you perform a mantle. Your triceps muscle becomes the agonist and the biceps becomes the antagonist
*Under high stress, such as during climbing, the antagonist may also undergo an eccentric muscle action to control movement at the end range of motion. An example could be moving SIDEWAYS (not upwards) as you are holding on to an undercling with on hand. You engage in both your bicep and tricep to generate the momentum and control.
Bring more stability and smoothness to your motion
Climb more efficiently to avoid being "pumped" or getting tired too quickly
Encourage proper muscle movement
Prevent strain and injury
Our calf muscles are used most of the time we are stepping on footholds as we are climbing. It becomes more engaged as you get better and step on very tiny footholds. As we use these muscles frequently, it is very important to strengthen the antagonist muscles - Tibialis Anterior. This will avoid muscle imbalance in our legs and ultimately prevent any injuries.
Perform each exercise for 20-30 seconds and have 1 minute rest before moving on to the next one.
Sideways-lying - Focus on pushing toes towards shin, squeeze for 2 seconds when you hit your max stretch and slowly release. Repeat.
Natural position - Same focus as above
Skip the stretch using the band and move to the Heel Walk next (skip 0:37-1:34 of the video)
Heel Walk - Slightly lean back, keep toes straight up and forward. Squeeze your Tibialis Anterior muscle the whole time.
Skip ankle weight exercise and move to the Weighted Stretch next (skip 2:11-2:24 of the video)
Weighted stretch - Sit on a chair. Elevate your ankle by using a small stool or stacked weights / books as a platform. Place ankle on the edge. Place weight between both feet using a dumbbell / filled water bottle / heavy book. Same focus as steps 1 and 2 as above.
Once you finish one set (4 different exercises), rest for 5 minutes and complete total of 3 sets.
