Physiorun Must Do Exercises
The essential movements every runner should have in their weekly routine — built for strength, speed and durability.
|
|
If you only had time for one class a week, what would you do?
This is that class. The Physiorun Must Do Exercises — a collection of movements chosen because they build the specific strength, control and athleticism that running demands. Not exercises chosen because they look good or feel hard. Exercises chosen because they work.
This class covers everything: foot and ankle preparation, calf and lower leg conditioning, loaded single-leg strength, hip control, and fast reactive footwork. Think of it as your running toolkit in one session.

Warm Up
|
| |
Foot Torques
Standing with feet flat, rotate the foot outward into the floor without actually moving it — creating a twisting torque through the arch and ankle. This wakes up the intrinsic foot muscles, loads the arch, and creates the tension through the lower leg that prepares you for everything that follows. Runners who skip foot preparation often miss this whole layer of stability. Two minutes here saves a lot of problems further up the chain.

Calf Drill — Forward & Backward Over a Fixed Foot
No step needed — foot stays flat and fixed on the ground. Drive the body forward over the foot and then control back, keeping the heel grounded throughout. This loads the calf and Achilles through a functional range of motion by moving the body over the ankle rather than raising and lowering the heel. It is closer to what actually happens during running — where the calf works to control forward tibial movement as the foot lands — making it excellent preparation before heading into the heavier strength work.

Full Set
|
Exercise 1 |
|
High Box Weighted Step Up
Step up onto a high box holding a dumbbell or kettlebell. The height and load together make this one of the most effective single-leg strength exercises for runners — it demands everything from the quad, glute and calf in one movement, while the trunk has to stay organised under the weight. High box step ups build the kind of raw leg strength that makes hill running, long races and heavy training blocks feel manageable rather than punishing.
|
Exercise 2 |
|
Single-Leg RDL
Hinge forward on one leg, keeping the back flat and the hip of the standing leg in control throughout. The single-leg RDL is one of the most running-relevant exercises you can do — it loads the hamstring, challenges balance, and trains the hip to stay strong and still when the body is in a single-leg stance. Every running stride is a single-leg landing. This exercise builds exactly the capacity that makes those landings safe and powerful.
|
Exercise 3 |
|
Band Side Step March
Band looped around the ankles or knees, step sideways with a high knee march on each rep. The band creates lateral resistance that forces the hip abductors and glutes to work to keep the pelvis level and the knee tracking correctly. The marching component adds a running-specific element — lifting the knee means you are also training hip flexor control and single-leg balance at the same time. A simple drill that hits a lot of the right muscles in one go.

Fast Feet Series
|
Exercise 4 |
|
Fast Feet — Forward
Quick, light, rapid foot contacts moving forward — staying on the balls of the feet with minimal ground contact time. This trains foot stiffness, reactive lower leg strength and the neuromuscular coordination that underpins running economy. Runners who are heavy or slow through their foot contacts lose energy with every stride. Fast feet drills teach the nervous system to be quick and snappy — and that transfers directly to faster, more efficient running.
|
Exercise 5 |
|
Fast Feet — Sideways
The same fast foot speed, now moving laterally. Runners are forward-moving athletes, but they also have to react to uneven ground, cambered roads and sharp turns. Lateral fast feet build the coordination, hip and ankle stability to handle those moments without losing control or loading up the wrong structures. This also challenges the adductors and abductors in a dynamic, reactive way that heavy strength training simply cannot replicate.
|
Exercise 6 |
|
Fast Feet — Figure 8
Quick feet tracing a figure-of-8 pattern on the ground — combining forward, lateral and diagonal movement into one fluid drill. The figure 8 adds the element of direction change, which demands rapid coordination between the feet, ankles and hips. It finishes the fast feet series by pulling all three planes of movement together, challenging the body in the same multidirectional way that trail running, racing and uneven terrain naturally do.

Why Every Runner Needs a Must-Do List — Not Just More Miles
Most runners who get injured were not doing anything wrong with their running. They were just only doing their running.
Running is a demanding, repetitive, single-plane activity. It loads the same muscles in the same direction thousands of times per session. It does not build lateral strength. It does not develop foot stiffness or reactive speed. It does not train the hips to control the pelvis under load, or the calves to absorb impact efficiently. It assumes all of that is already there.
When it is not — when those foundations are missing — something gives way. A knee. A calf. An Achilles. A hip. The injury site varies but the root cause is often the same: the body was not strong or resilient enough to handle the load running was placing on it.
That is what a must-do list solves. Not a random collection of exercises you found online — but a targeted set of movements chosen specifically to fill the gaps that running leaves behind. Foot and ankle work. Hip control. Single-leg strength. Reactive speed. Lateral coordination.
Done consistently — even once a week — this kind of work changes what your body can handle. More mileage. Faster sessions. Hillier routes. Harder races. With less breakdown.
More miles makes you fitter. Must-do exercises make you durable. You need both.

Top Tip of the Week
Add Fast Feet Before Your Next Run
Most runners warm up with a slow jog and a few stretches. But fast feet drills — just 2 to 3 minutes before you run — can switch the nervous system on in a way that slow jogging never does.
Quick foot contacts prime the calves and ankles for the reactive loading of running, sharpen your coordination and proprioception, and get the brain and legs communicating at the speed running actually demands. Runners who do this often report that the first mile feels better and the legs feel more alive from the start.
The tip: add 30 seconds of fast feet forward, 30 seconds sideways and 30 seconds figure 8 at the end of your warm-up before your next run. Do it for two weeks and notice whether your first mile feels different. It usually does.

This Class Is Ideal For Runners Who Want To:
| Build all-round running strength |
Improve single-leg strength and control |
| Develop faster, lighter feet |
Strengthen the foot and calf properly |
| Reduce injury risk |
