Many footballers lift well in pre-season and then stop once matches start. By mid-season much of that strength can fade, right when hamstring and groin injuries tend to climb.
Research generally shows that strength can be maintained with relatively low volume, often one or two short sessions a week, as long as intensity stays fairly high
Place the main lift early in the week, ideally three or more days before the match
Prioritise a few big patterns: a squat or split squat, a hinge, a hamstring exercise and an upper-body push or pull
A minimal in-season template, around 30-35 minutes: rear-foot elevated split squat 3×4-6 per leg, Romanian deadlift 3×5, Nordic curls 2-3×3-5, a pull-up or row 3×6, and a short core exercise. Load heavy enough that the last rep is challenging, but stop well short of failure.
With two matches a week, it can drop to one or two exercises done on the first training day.
