Bottom-Focused Calf Raises ~ Ellington Darden
Are your calves stalled at a certain level of development? Here’s a neat technique I learned from Dan Ilse, who won Mr. Texas in 1961. Dan was 5’10" tall and weighed 200lbs – and he had impressive, diamond-shaped, 18" calves.
Ilse thought the key to stimulating calf growth was to pay more attention to the stretched position than the contracted position. He emphasized the stretch in a unique way. He divided the standard calf raise into two parts: the bottom 1/2 and the top 1/2. He began his set by doing 12 bottom-1/2 reps; followed by 12 top-1/2 reps; followed by 12 bottom-1/2 reps.
Overall, he performed twice as many bottom-1/2 reps as he did top-1/2 reps. When he could do 15 reps in each of the 3 divisions, he upped the resistance.
Try the bottom-focused movements the next time you do calf raises and see if they don’t make a difference in your growth stimulation.
Keep all your 1/2 repetitions slow and smooth.
