Hip Flexors
Sitting shortens them; they return the favor by tugging your lower back. Keep them long and strong.
Build it
Exercise
Mountain Climber
Part cardio, part core, part hip-flexor work - mountain climbers earn their spot in any time-crunched session. Thirty seconds gets your heart rate up faster than most things you can do in a living room.
Exercise
Banded Psoas March
Sitting all day leaves the deep hip flexors weak and cranky. This lying march against a band strengthens them directly, which pays off in a smoother stride, easier stairs, and a lower back that complains less.
Exercise
Standing Knee Raise Hold
Stand tall, lift one knee above hip height, and hold it there without leaning back - harder than it sounds after years of chairs. It builds the hip strength and single-leg balance that make stairs, hikes, and playground chases feel easy.
Also works the hip flexors
Exercise
Dead Bug
It looks silly and works brilliantly. The dead bug trains your core to stay braced while your arms and legs move - exactly what happens when you're carrying, reaching, and bending all day. It's also one of the safest ab moves for a stiff lower back.
Exercise
Hanging Knee Raise
Hanging from a bar and raising your knees builds serious ab strength while decompressing your spine and toughening your grip as a bonus. It's the natural next step once planks and dead bugs feel easy.
Exercise
Bicycle Crunch
A floor classic that works the obliques through rotation - the movement pattern behind twisting to grab something in the back seat. Done slowly and with intent, it's far more effective than the frantic version most people rush through.
Free it up
Stretch
Couch Stretch
Rear knee against the couch, shin up the backrest - the deepest hip-flexor and quad stretch you can do at home, using the exact piece of furniture that made you tight. Sitting shortens the front of the hip; this is the antidote, and it's intense.
Stretch
Kneeling Hip Flexor Stretch
The half-kneeling lunge is the friendliest way to open hips that spend eight hours folded at ninety degrees. Tight hip flexors tug on the lower back all day - freeing them up is one of the highest-value stretches a desk dad can do.
Stretch
World's Greatest Stretch
A deep lunge with a rotation that hits the hip flexors, hamstrings, and torso in one flowing move - the name is only slightly an exaggeration. If you have ninety seconds before a workout or after waking, this is the one stretch to do.
Stretch
Cobra Stretch
Press your chest up off the floor and give the whole front of your body - abs and hip flexors - the extension it never gets in a chair. It's the single best counter-shape to a day of sitting, and it feels great first thing in the morning.
Stretch
Standing Quad Stretch
Heel to hip, knees together - the classic quad stretch that takes twenty seconds and needs nothing but a wall for balance. Loose quads take pressure off the knees before and after runs, hikes, and backyard sprints with the kids.
Stretch
Figure-Four Stretch
Ankle over the opposite knee, pull the legs in, and the deep glute muscles that stiffen from sitting finally let go. Tight glutes and deep rotators are a common hidden driver of lower-back grumbling - this is their release valve.
Stretch
Pigeon Stretch
The deepest glute stretch in the catalog: one shin folded in front, the other leg extended behind. It reaches the stubborn outer-hip tissue that figure-four can't quite touch - the payoff after leg day or a long week in the car.
Fix what hurts
Physio
Standing Hip CARs
Controlled Articular Rotations for the hip: standing on one leg, you draw the biggest slow circle you can with the other knee, lubricating the joint through its full range.
Physio
90/90 Hip Switch
A seated drill that rotates both hips between two ninety-degree positions, restoring internal and external hip rotation that long sitting slowly erases.
