Exercise guidance based on established strength-training principles and practical programming.
The one and a half RDL adds a half rep at the bottom of each full rep, doubling time under tension in the stretched position where hamstring activation is highest. You lower fully, come up halfway, lower again, then stand completely—that entire sequence is one rep. This technique builds strength and size through increased work in the most demanding portion of the lift.
When to use it
Use for advanced hamstring training techniques.
Who it's for
Intermediate to advanced lifters wanting intensity.
Lower to full depth, rise only to knee height, lower again to full depth, then stand all the way up. Count this entire sequence as one rep. Use lighter weight than regular RDLs since the additional half rep dramatically increases difficulty.

We slot it into the right day with sets, reps, and progression you can follow.
Stand holding barbell at thighs.
Lower bar to mid-shin with hip hinge.
Come up halfway to knee level.
Lower again to mid-shin position.
Stand all the way up to complete rep.
That full sequence equals one rep.
Increases time under tension dramatically.
Use lighter weight than standard RDL.
Focus on the bottom half of movement.
Program one and a half RDLs during hypertrophy phases when you want maximum time under tension in the stretched position, for variety from standard RDLs, or when trying to break through plateaus. Use moderate weight. They pair well with leg curl variations.
Not returning to true halfway point.
Cutting the range of motion short on the One and a Half RDL can reduce the training stimulus for your Hamstrings. Use the largest comfortable range you can control without changing the intended setup.
Using same weight as regular RDLs.
Loading more weight than you can control on the One and a Half RDL often creates compensations that shift work away from your Hamstrings. Reduce the load until each rep follows the intended path.
Rushing through the half rep portion.
Rushing through the One and a Half RDL makes it easier to lose position and harder to keep tension on your Hamstrings. Slow down enough to control both the lifting and lowering portions of each rep.
Intermediate to advanced lifters wanting intensity.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 8 reps. Rest 90 seconds.
