Every so often I change my typical exercise routine. This week I am focusing on tension strength training, slow steady movements in each direction. Typically a single rep takes maybe a second or so in each direction, this week I'm going to take five second reps each direction. Another benefit of lifting that way is it moves my workout into the cardio zone which I certainly need more of.
It's one of my least liked styles of lifting but incredibly beneficial, also less damaging to my aging body than moving heavy weight.
