Platform Hamstring Slides
Also works: Glutes
Lying on your back with one heel on a towel or slider, you drag that heel toward your backside against nothing but floor friction. It is knee flexion for the hamstrings with no machine and no weight stack, and its real value is as a rehab-adjacent single-leg curl you can run daily on a smooth floor.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Find a smooth floor: laminate, wood, tile. Carpet kills the slide and turns this into an isometric.
- Lie flat on your back, legs straight, arms at your sides with palms pressed down for stability.
- Put a folded gym towel or a furniture slider directly under one heel, not under the calf.
- Press your lower back lightly toward the floor so your pelvis does not tip as the leg moves.
- Keep the non-working leg straight and still on the floor — it is a reference line, not a helper.
Every rep
Breathing & tempo — Breathe normally throughout; nothing here needs a brace. One second in, one second squeeze, three to four seconds out.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Bodyweight and friction only. Progress by slowing the return to a four-second count, then by adding a two-second hold at full knee flexion, then by sliding both heels at once so one leg is not resting. When even the two-legged version feels easy, you have outgrown the drill — move to a glute ham raise or a lying leg curl.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Move to a hard smooth floor, or swap the towel for a plastic furniture slider. If you only have carpet, use a ball leg curl instead — the surface is the whole mechanism here.
Count three seconds on the way out. Friction gives you almost nothing on the concentric, so the slow eccentric is where the training effect lives.
Keep your backside on the floor and ribs down. If you want more load, do a single-leg glute bridge as a separate movement rather than blending two exercises into one sloppy rep.
Shorten the range to the point where it is only a working ache, and add 5 cm of slide per session. Sharp is a stop signal, not a progression cue.
Why bother
The hamstrings do two jobs: extend the hip and flex the knee. Every hinge you own — deadlifts, good mornings, swings — trains the hip job and almost none of them train the knee job. A slide fills that gap with the least equipment possible, because the only resistance is the friction of a towel on a wooden floor.
Because the resistance never exceeds what a towel will give you, this tolerates volume that a leg curl machine does not. That makes it a reasonable choice when a hamstring is irritable and you want blood and range through knee flexion without the shear of a loaded hinge. It is not a strength builder for a healthy trained leg — friction on a towel tops out fast.
Where it fits
Treat it as accessory or warm-up work, not a main lift. Two or three sets at the end of a lower-body day, or daily in low volume if you are working back from a strain. Do not slot it in place of Romanian deadlifts — it trains the other half of the muscle, so run both.
If this one isn't it
No kit, too hard, or too easy — here's where to go instead.

Asked and answered
Do I need actual sliders or is a towel fine?
A towel is fine on wood or laminate. Sliders are more consistent on tile, and a paper plate works surprisingly well on carpet-free surfaces. What matters is that the heel glides without catching — a heel that sticks and releases turns a smooth curl into a series of jerks the hamstring has to catch.
Can I do this with a pulled hamstring?
Often yes, and it is one of the earlier things people can tolerate, because the load is minimal and you control the range precisely. Keep it to a working ache, never sharp, and stay well short of the range that reproduces the injury. If it is a fresh grade II or worse, that is a conversation with a physio, not a website.
Is this as good as a leg curl machine?
No, not for building strength. A machine gives you progressive resistance you can actually load; a towel gives you friction that never increases. Use slides for volume, warm-up, and rehab, and use the machine or a glute ham raise when the goal is a stronger hamstring.
Should I be doing these on both legs at once?
Start single-leg, because one heel on a towel is already close to the ceiling of what friction provides and you can watch the pelvis on the working side. Two heels at once roughly doubles the drag and removes the resting leg, which is the main progression this drill has left once the slow return stops being hard. It is the last step before you need a machine or a glute ham raise.
