It's not for everyone, and it doesn't directly translate to real cycling. But there are some benefits. Last year, I sold my trainer and started doing group spins at the "Y" a couple times a week (at my age, I get a free membership). Turns out two of my former collegues were in the class, and we started having coffee after the sessions. At the end of the winter, my transition to regular biking was easier, and I found my cadence and tempo skills had greatly improved. The instructor was very encouraging and played a good mix of music (classic rock to modern stuff). In all, it was fun and it kept me moving through the winter. Hugely more interesting and motivating than riding the trainer in the basement (and I had a good setup). It was just a matter of accepting it for what it was.
