Speed
Most guys who pull a hamstring at a company softball game didn't get hurt because they were old. They got hurt because the last time they ran at full speed was eleven years ago, and their body had no idea what was coming.
Speed is a skill and a quality. You don't lose the skill — you'll still know how to lean, drive, and plant. What you lose is the tissue tolerance and the nervous system's willingness to fire hard. Both come back, but they come back on a schedule, not on a dare.
Former athletes lose speed faster than strength, but it comes back quickly when it is trained on purpose. Sprint once or twice a week, fresh, at the start of a session. Begin with build-ups at 70–80% and short accelerations of 10–20 metres, add deceleration and cutting drills in week three, and only open up to near-max efforts after four weeks of clean work. Pair it with hamstring and calf strength, keep total sprint volume low, and rest fully between reps.
Speed work is only speed work when you're fresh. Tired sprints teach you to run slow and give your hamstrings the worst possible combination: high speed, low control.
Jogging a lap and swinging your leg a few times isn't a warm-up for sprinting. Build heat, then rhythm, then speed.
Acceleration is the safest place to start. You're pushing, not reaching, so the hamstrings aren't being stretched at high speed.
Most non-contact injuries happen when you slow down or change direction, not when you speed up. Teach your body to stop before you ask it to cut.
If the first four weeks felt clean — no tight hamstrings the next day, no nagging calves — you've earned some real speed.
Sprinting well needs strong hamstrings, stiff calves, and hips that don't collapse. Add these twice a week on lifting days: Nordic hamstring lowers 3 x 4 (or band-assisted), single-leg Romanian deadlifts 3 x 8, bent-knee calf raises 3 x 15, and split squat jumps 3 x 4 per side once you're comfortable.
If you feel a sharp grab in the back of the thigh, stop that day. Don't test it with one more rep. A tight hamstring is a two-day problem; a strained one is a six-week problem.
Watch a good acceleration and there is less drama than most people expect. The first steps are forceful, but the face and shoulders stay quiet. Former athletes returning to speed often try to manufacture intensity by tightening everything. That tension shortens the stride and makes each contact louder. Think push the ground away, then let the body rise naturally.
Film one rep from the side if you can. You are not looking for perfect mechanics; you are checking that each repetition resembles the last. If the torso pops upright immediately, the feet reach far ahead, or one side looks hurried, reduce the speed and regain rhythm. Technical consistency is the permission slip for greater intensity.
End on the best rep, not after it. Speed sessions feel short because the nervous system needs full recovery to produce quality. When another sprint would mainly satisfy your appetite for work, move on to strength or go home. Leaving a little unused speed is how you return two days later with healthy hamstrings and a better chance to improve.

A free, structured training week that keeps strength and athleticism moving in the same direction.
Unlock ProgramYes, much of it. Acceleration and change of direction respond quickly to six to eight weeks of consistent, fresh sprint work combined with lower-body strength training. Top-end speed declines slowly with age, but most former athletes are far from their current ceiling.
Once or twice a week. Speed depends on quality, not volume, so a few fast reps with full rest beats a long session of tired running.
Warm up properly, start with acceleration instead of flat-out sprints, progress intensity over several weeks, and strengthen the hamstrings with exercises like Nordic lowers and Romanian deadlifts.
Yes. Deceleration and cutting drills keep your knees and ankles prepared for real life — pickup games, playing with your kids, or catching yourself on a trip — and they're where most non-contact injuries happen.
