A real warmup raises core temperature, activates the nervous system, and rehearses the movement patterns you're about to use — it does not mean holding static stretches. Static stretching before power or speed work can temporarily reduce force output, which is the opposite of what you want before a lift or a sprint. A good warmup is progressive: general movement, then dynamic mobility, then activation drills that match what's coming next.
Most warmups are movement theater. A few laps, some static stretches, maybe a lunge or two, and then straight into the workout. It feels like preparation, but it doesn't actually prepare the body for what's about to happen.
A warmup has one job: raise your capacity to perform for the next 60-90 minutes. That's a specific physiological target, and most warmup routines aren't built to hit it.
Why Doesn't Static Stretching Belong Before Training?
Holding a stretch for 20-30 seconds before a lift or a sprint session temporarily reduces the muscle's ability to produce force. That's the opposite of what you need right before power or speed work. Static stretching has a place — just not as the first thing you do before you ask your body to move fast or lift heavy.
A warmup should raise your capacity to perform, not just raise a sweat.
What Should a Warmup Actually Include?
A real warmup builds in stages, each one setting up the next:
- General movement to raise core temperature — light jogging, skipping, or bike work
- Dynamic mobility through the ranges you'll use — leg swings, walking lunges, hip openers
- Activation drills that wake up the nervous system — short accelerations, jumps, or band work targeting the muscles you're about to load
By the end, you should feel primed, not tired. If your warmup leaves you gassed before the real work starts, it's doing the wrong job.
Should the Warmup Change By Session?
Yes. A warmup before a max-effort lift looks different from one before a sprint session or a game. The principle stays the same — general to specific — but the activation piece should rehearse the exact pattern coming next. Squatting heavy? Warm up with bodyweight squats and light activation for the hips and core. Sprinting? Warm up with acceleration drills and short build-up runs, not just static hamstring stretches.
This is a pattern we see often at FPC: athletes who show up, do a generic five-minute stretch routine, and then wonder why their first few reps or sprints feel disconnected and slow. The body wasn't actually prepared — it was just loosened.
What Should an Athlete Do Differently?
Treat the warmup as programmed, not optional or improvised. Ten to fifteen minutes, staged from general to specific, ending with movement that mirrors what's about to happen. Save static stretching for after training or for a separate mobility session. Done right, a warmup doesn't just prevent injury — it makes the actual training session more productive from the first rep.
Frequently Asked Questions
Should you stretch before working out?
Static stretching (holding a stretch) before power or speed work can temporarily reduce force output, so it's better saved for after training. Dynamic mobility and movement-based warmups are more effective before you train.
How long should a warmup be?
Ten to fifteen minutes is usually enough — general movement to raise temperature, dynamic mobility through the ranges you'll use, then activation drills specific to the session.
Does a warmup actually prevent injury?
A properly staged warmup reduces injury risk by raising tissue temperature and priming the nervous system for the movement patterns coming up, but it should also improve performance in the session itself, not just protect against injury.
Should the warmup be the same every day?
No. The general structure stays the same, but the activation portion should match the session — different for a heavy lift day than for a sprint or game day.
