Nothing magical will happen after age 25. No dead end or point of no return. It's about what's important for you - your priorities. Just get a notepad and log what you did on your workout, then try to beat the result on the next. Commit to two workouts a week and you're set.
And you should enjoy working out, not avoiding it. Working out is great. You can put your anger and energy into the weight, watch as you're getting stronger(LOG HELLO!) and leaner.
In 2005 I barely had any equipment and a schedule that makes a sniper in Baghdad appreciate his job. And I worked out at least 3x/ week(mostly 5-4x!!). I cooked three times durring the week to have decent meals.
Get your pussy ass together and start busting out reps. I don't care if today you just do three sets of deadlifts and call it a day. Or maybe you wake up and decide to try every possible variation of the bicep curl - just do some shit with weights and love it! Watch a Schwarzenegger flick.
