Don’t focus so much on the weight load at first, but more on gradual progression, technique, and safety. You don’t want to jump right into super heavy sets and place an unnecessary load on the ankle and foot. As over time this can cause long term issues.
Instead, use light to medium heavy loads and work on range of motion, and feeling the contraction in your calf muscles. Then, you can implement progressive overload via a combination of adding extra reps with the same weight and increasing the resistance.
Overtime, you’ll get stronger and your body can better adjust to higher intensity training.
