I have a couple questions on calf training.
What would be the differences between using a standing calf machine and a horizontal leg press for calf raises?
By preforming calf raises with feet wide apart, shoulder width, an inch apart, etc. what different part of the calf do they target, if it is even beneficial?
Would holding at the top ROM of a calf raise for over 5 or so seconds be harmful for the knees? When holding when the calf is fully contracted for long periods of time 6-15 seconds be beneficial?
Also, since the gastrocnemius is primarily fast twitch and the soleus is primarily slow twitch, would it be best to train them accordingly (gastroc - low reps, soleus - high reps), what about training gastrocnemius for both fast and slow twitch, same with the soleus?
