Approaching retirement from full-time work, the last thing I would have foreseen doing was to take up powerlifting and get involved in competitions. I had plans to spend more time walking and climbing in the Alps, but increasing knee problems (osteoarthritis) around 2014-2015 put that on hold. I stopped doing Crossfit classes in 2015 and instead started to focus on weight training apart from squats.
I had also been reading various books and research relating to exercise and ageing, and became convinced that to maximise my health and functioning into older age I needed to maintain and improve my strength, and that this was probably more important than the endurance cardiovascular training that I had been doing for many years.
I found that I really enjoyed training with heavy weights and low repetitions (usually in range 3-6) and that my knees felt a lot better after a workout. With some coaching on good technique, I was able to substantially increase the weight and volume I was working with and would often leave the gym with an endorphin high and pain-free knees. Occasional lower back pain (related to an old injury during jujutsu training) also became rarer.
