Another great suggestion from Beth Skwarecki: A lot of beginners worry about the optimum number of reps, what supplements they need, the best workout schedule, and other minutia. Forget all that. As a beginner, it literally doesn’t matter.
The important thing is doing it—putting on the sneakers, rolling out the mat, hopping on the bike, and doing it. If you’re only good for five minutes, that’s better than no minutes, and you can do 10 minutes tomorrow. Or four minutes tomorrow and seven minutes on Wednesday—as Beth puts it, “Just get in the gym and do something.”
