Calves are considered the most difficult body part to develop, but it does not take a miracle to make your calves grow into cows! To acquire a decent pair of calves, you must be equipped with the correct principles on how to train them, and the motivation to train them intensively. Intensive calve training can be very painful with very little reward and will leave the calves feeling tender for days after. Since your calves are incredibly strong and carry your bodyweight throughout the day with ease, you must hit them with far heavier weights than they are accustomed to shock them. Use every high-intensity principle possible to force them into growing.
