THE HAMSTRINGS
A complete 3D Muscle Lab lesson — the same format used in the full course. See how it works, then decide if it's right for you.
What you’ll learn
Your hamstrings in full 3D
Most practitioners have a rough idea of what the hamstrings do — but seeing them in 3D changes everything. You'll learn exactly where each muscle attaches, what it does, and how to remember it.
- Biceps Femoris
- Semimembranosus
- Semitendinosus
This is the bony landmark lesson for the group — where each muscle attaches on the skeleton, in 3D with audio, followed by a quiz so the information actually sticks. About 15–20 minutes. Origin, insertion and action get their own lesson right after this one.
HOW THIS LESSON WORKS
- 1Preview the bony landmarksClick each toggle to reveal where the hamstrings attach on the skeleton. Try to recall the answer before opening it — that's the first layer of memory work.
- 2Watch the lectureDavid walks you through every hamstring attachment site on the skeleton, in plain language, with the 3D model on screen throughout.
- 3Look, listen and readEach landmark gets its own 3D image card with audio. Click play, look at the model, and read along. Three input channels at once = better retention.
- 4Test yourself with the quizFive questions on what you just covered. Answer them and see your score — this is what makes the information stay with you, not just for the exam, but for when you're in the room with a client.
The three muscles this group is built from

ISCHIAL TUBEROSITY - Origin
Ischial Tuberosity
All three hamstrings originate from the ischial tuberosity — the bony landmark you sit on. The long head of biceps femoris, semimembranosus, and semitendinosus all share this common origin point on the pelvis.
LINEA ASPERA - Biceps Femoris Short Head Origin
Linea Aspera
The short head of biceps femoris has a separate origin — the linea aspera, a rough ridge running down the posterior femur. This is what makes the biceps femoris unique among the hamstrings: it crosses only the knee, not the hip.
HEAD OF FIBULA - Biceps Femoris Insertion
Head of the Fibula
Biceps femoris inserts on the head of the fibula at the lateral side of the knee. This is why biceps femoris can assist with lateral rotation of the knee — something the medial hamstrings can't do.
PES ANSERINE - Medial Hamstring Insertions
Pes Anserine
Semitendinosus inserts at the pes anserine — "goose foot" — on the medial tibia, alongside gracilis and sartorius. Semimembranosus inserts slightly higher on the medial tibial condyle. Both assist medial rotation of the knee.
