People love to argue about the “optimal” time to train. The research-backed truth is refreshingly simple.
The best time is the one you’ll stick to
Differences between morning and evening training are small and individual. The time that lets you train consistently will out-perform the theoretically “optimal” time you keep skipping.
The case for morning
Morning workouts get it done before the day derails your plans, and many people find they’re more consistent early. The downside: you may feel a bit stiffer and need a longer warm-up.
The case for evening
Strength and power tend to peak slightly later in the day, and you’re fully warmed up from being awake. The risk is that work and life can crowd it out.
