Q: Should I lift weights before or after my run?
A:
Ideally,
you should run and strength-train on separate days—or at least wait
several hours after running to hit the weights. That way, you’ll have
the energy to get the most out of each activity, your form won’t
suffer, and you won’t risk injuring yourself from being overtired.
But if you’re short on time and have to squeeze both in, run first, then do two sets of 12 to 16 reps of each move, using slightly lighter weights than usual.
