O well, starting small is key to building a habit without crashing. Aim for consistency over intensity, so let's keep this to 30 minutes a day, three to four times a week at first. Focus on a mix of cardio to build endurance and simple strength moves to counteract all that sitting. For example, start with brisk walking, which you can do right after work to shake off the day. Here's a simple weekly plan to get you going: On Mondays and Wednesdays, do 20 minutes of walking at a pace where you can talk but feel your heart rate up, followed by 10 minutes of bodyweight exercises like squats and push-ups against a wall. Tuesdays and Thursdays could be lighter with yoga stretches to loosen up your hips and back from desk hunch - try child's pose for a minute or two to really feel the release.
Take Fridays off or do a gentle 15-minute walk if you're up for it, and weekends are for something fun like a short hike or biking to keep it enjoyable. Rest on the other days to avoid burnout. Track your progress in a notes app to see how those stairs get easier over time, and remember to listen to your body - if something hurts, ease up. Drink water throughout and maybe add a protein snack post-workout to help recovery. In a month, you'll likely notice more energy at work too.
