Runners may avoid weight resistance training because it feels too slow, is usually indoors, and seems to lack the respiratory, skin pore, and circulatory opening that comes with dedicated running.
Here’s a simple approach you may have forgotten: Buffer your strength training exercises with jump rope intervals. This will help you work on your calve muscle strength while opening your lungs, heart and skin pores. Boxers do road work, weight resistance, and plenty of jump roping with good results. You can too.
