You don't need a cage, a coach, or a machine to build a real swing. You need a tee, something to hit into, and fifteen honest minutes. Here are six drills that cover the whole swing — load, stride, separation, path, and extension — plus how to film them so you know they're actually working instead of just feeling like they are.

The six

Mirror Load Checks — no tee needed. Slow-motion loads in front of a mirror: weight gathering into the back hip without drifting past the back foot, hands riding back calm. Ten perfect loads. This grooves the gather that a lot of swings skip entirely — you can't unload a spring you never loaded.

Walk-Through Swings — two walking steps into a tee swing. Ten reps. Teaches a moving load and natural rhythm instead of a frozen, muscled start.

Stride-and-Hold — load, stride, freeze at front-foot landing for two seconds (weight inside the back hip, hands back, nose behind the belt buckle), then swing. Ten off the tee. The freeze is impossible to fake, so it teaches "land ready" and cures both the lunge and the over-stride.

Hip-Lead Separation Turns — bat across your hips, stride, then fire the hips while the shoulders stay closed a beat longer. Three sets of eight, no ball. This is where bat speed is made: belt buckle first, shoulders late.

Top-Hand / Bottom-Hand Tee Work — one-handed swings with a short bat or choked grip, each hand learning its job through contact. Eight each hand. Cures casting and roll-over by teaching the direct path and the drive through the ball.

High-Tee Line Drives — tee at the top of the zone, hard line drives without popping up. Ten balls. Forces a level barrel and full extension through the ball, and fixes both the uppercut and the cut-off swing.

Build a session, don't do all six every day

Pick two or three that target your leak, not the whole menu. If your swing starts flat-footed, Mirror Load Checks and Walk-Throughs. If you spin as one block, Separation Turns. If you cut the swing off, High-Tee Line Drives and Top-Hand/Bottom-Hand. One thing at a time beats a laundry list every session.

A safety word: keep everything light and rhythmic, especially if you're younger. Never chase bat speed with effort — chase it with order and rhythm. A med ball you can throw with intent, a bat you can control, no weighted-bat heroics by the ounce.

Film it so you know it's working

Here's the trap with home drills: they feel like progress whether or not they are. The camera settles it. Once a week, set your phone at chest height, 12 to 15 feet away, open side, whole body and bat in frame, and film one tee swing. Let CoachVision read your load depth, your stride, your separation and your extension — and if the drill you've been grinding moved a number, that's the most motivating sentence in practice. One honest note: the tracker sees your body, not your bat or the ball, so "contact" is your hands' peak speed and a dry or tee swing scores just like a live one.

Fifteen minutes, two or three drills, one filmed swing a week. That's a whole off-season built in your garage.
