Should You Train Hamstrings Twice a Week?
Yes for most lifters. Split Romanian deadlifts and leg curls across two days. One marathon posterior-chain session is leftover fatigue. Squats count — they do not finish the job.
Short answer: yes — two quality hamstring days beat one endless posterior-chain dump
Should you train hamstrings twice a week? For most healthy adults who lift for size, a stronger hinge, or a sprint that still has a last gear, yes. The hamstrings are hip extensors and knee flexors. They grow from weekly hard sets you can repeat, not from one 40-minute catalog of Romanian deadlifts, good mornings, lying curls, seated curls, and back extensions that leaves your low back cooked and Friday’s squat a shrug. Split the direct work across two days with at least one easier or rest day between the hard hinge sets. One well-built lower-body day still grows muscle, especially if you are new. It is just a worse way to pile quality volume once the last curls are theater and your hips already worked on every deadlift.
This is not today’s creatine-if-you-play-soccer article. That page is a daily 3 to 5 gram monohydrate for sprints and cuts on the pitch. It is also not the November 1 two-glute-day piece, the October 31 two-arm-day article, the October 30 two-shoulder-day article, the October 29 two-back-day article, the October 28 two-chest-day article, or the October 13 two-leg-day page. Those asked hip-thrust frequency, biceps and triceps frequency, delt frequency, pulling frequency, pec frequency, and whether one wrecked Monday can hold quads, hamstrings, and glutes at once. The October 14 squat-and-deadlift pairing and the October 18 deadlift-on-back-or-leg-day article still own where the bar goes in the hour. This page only answers hamstring frequency across seven days: you already hinge or curl, a feed said “hamstrings once, annihilate them,” and you want to know if a second hamstring-focused day is extra growth or extra junk volume on a posterior chain that already works every squat, lunge, and pull.
This is general training and sports-nutrition education for healthy adults, not medical advice and not a hypertrophy guarantee. Sharp joint pain, sudden swelling, chest pain, dizziness, numbness, or form that feels unsafe are stop signs. People returning from a hamstring, adductor, low-back, or knee issue, who are pregnant, under 18, or following a clinician- or coach-set plan should use that plan instead of copying a twice-weekly RDL template. Two hamstring days do not guarantee a thicker posterior chain, a heavier deadlift, faster sprints, or muscle you did not recover from. Progressive loading, enough protein, sleep, and calories still outrank the calendar.
- Default: two recoverable hamstring-focused sessions a week with a day between the hard hinge work
- This is hamstring frequency, not soccer creatine, whole-leg Monday, or pairing the squat and the deadlift
- One long posterior-chain dump still works; it is usually a worse way to get quality volume
- No split, scoop, or creatine tub guarantees muscle
Frequency is a volume tool — squats already work the hips, they do not finish the hamstrings
A 2016 systematic review and meta-analysis by Schoenfeld, Ogborn, and Krieger in Sports Medicine found that training a muscle twice a week produced more hypertrophy than once a week when they pooled the available trials, with a larger effect size for the higher-frequency condition (about 0.49 versus 0.30). A 2019 follow-up meta-analysis by Schoenfeld, Grgic, and Krieger in the Journal of Sports Sciences, covering 25 studies, then made the important cut: when weekly volume was equated, frequency itself did not significantly change muscle growth. Higher frequency helped in the studies where extra days also meant extra sets. Twice a week is not magic. It is usually the schedule that lets you do a real weekly dose of hard hamstring work — often discussed in the 8 to 16 hard-set neighborhood for trained posterior chain, with some intermediates sitting lower because a true RDL is expensive — without turning Wednesday into a 20-set hinge that your low back remembers on Friday’s squat.
Hamstrings make that arithmetic messier than a clean “arm day.” Squats, lunges, and split squats already tax the posterior chain if you actually sit into the hip instead of bouncing off the knees — but they are still a quad-dominant pattern for most people. Conventional deadlifts tax the hip extensors if the hinge is a hinge, not a shrug. They do not finish the job if you never train knee flexion. Romanian deadlifts, stiff-leg deadlifts, and good mornings load the hamstrings long. Seated curls, lying curls, and Nordic-style work load them as knee flexors. Counting every squat as a finished hamstring program, then adding a second 12-set smash of RDLs, is how people cook the same hip twice and call it frequency. Ignoring the compounds and living on light band curls is the other error: you never loaded the tissue that actually grows.
Do not confuse two hamstring days with hinging every day. Hard hip extension is not a daily identity and it is not the October 21 consecutive-day article. That page asked whether Monday and Tuesday can both tax the same tissue. This page asks how many quality hamstring sessions belong in a normal week. Muscle protein synthesis after a session does not stay elevated all week, but that is not a license to beat a cranky proximal hamstring into a third smash. Curls often feel recovered sooner than a heavy RDL because a machine set is not a 315-pound hinge. The joint and the low back do not always agree. If the bar is already drifting, the lumbar spine is the limiter instead of the hamstrings, or the muscle barks on every walk-in, you did not earn extra growth. You earned a recovery bill. If the second day is so easy it never needs recovery, it is also too easy to be the growth work.
- 2016 pooled data favored twice weekly versus once; 2019 volume-equated data found little independent frequency effect
- Weekly hard sets still lead; frequency mainly helps you do those sets well
- Do not count every squat as a finished RDL program, or every light curl as a finished hinge
- Soreness and a pump are not a scoreboard; two hard days still need a gap between them

Keep two hamstring days — skip daily RDLs as a personality
Keep two hamstring-focused sessions if you already lift three to six days a week and want more quality posterior-chain work than leftover squeeze after a wrecked quad day. A simple pattern is one hinge-biased day — a Romanian deadlift, stiff-leg deadlift, or hip hinge you can load, then a curl if quality remains — and one curl-biased day two to four days later: seated or lying leg curls you can progress, then a lighter hinge or back extension if the hips are still honest. You can flip the emphasis. You cannot dump every machine onto both days and call it frequency. Upper/lower already does a version of this: two lower days, each with a real hip-extension or curl set. Six-day PPL does it if you actually recover between the two leg days and you do not stack a third “hamstring destroyer” on top. Full-body three days a week can hit a hinge or a curl each session at lower per-day volume. You do not need a seventh posterior-chain dump on top of that. You need the hard sets to stay hard, with the lumbar spine quiet and the hamstring doing the work.
Skip stacking two near-failure RDL smash sessions 18 hours apart, especially if you also ran a hard squat or conventional deadlift in that window. That is the October 21 consecutive-day problem plus the October 13 whole-leg overlap, not extra frequency. Skip adding a third near-failure hinge day if your low back or proximal hamstring already complains on the second. Skip replacing progressive overload with extra curl volume because the first day “didn’t feel the burn.” Extra isolation can be useful leftover work. It is not a second hamstring day if you already hinge twice and the extra sets are junk. Skip treating one hamstring day as a moral identity. One well-run session still grows muscle if weekly sets, food, and sleep are in place — it is just a narrower way to progress once you need more quality work. Skip dropping protein or creatine because you added a Saturday curl. The signal is still hard sets you recover from. The powder does not replace the second day, and the second day does not replace food.
Do not drop direct knee-flexion work because last week’s pump was smaller. Pumps are not a hypertrophy lab, and a thick hamstring pump is easy to fake with a short range. Do not chase a daily Nordic streak because a feed said hamstrings recover in 24 hours. Two honest sessions beat seven ugly ones. If a clinician or coach set a hamstring, knee, or return-to-sprint limit, extra hamstring days are not a size strategy. Pause and use that plan instead of copying a 20-set internet chart on a tissue that is already loud. If sleep is wrecked and the bar is slow for two weeks, cut a few isolation sets from one of the two days before you add a third hamstring session.
- Best fit: two hamstring-focused days, hinge-biased then curl-biased, with a gap between them
- Weak fit: daily RDLs, two smash hinge days in a row, or a third posterior-chain day on top of six-day PPL
- Keep hinging first; extra light curls do not replace progressive Romanian deadlifts
- Clinician-directed limits beat any twice-weekly template
Buy creatine for the hard sets — not a “hamstring-day stack”
Fix the habit in this order. First, pick the weekly hamstring slots you will not skip — two days with a gap, not a fantasy seven-day Nordic specialization. Second, put a hard hinge or curl first while you still have hip quality, then one secondary pattern, then stop. Third, keep protein in a real training range and count food first. Fourth, leave creatine as a separate 3 to 5 gram monohydrate habit if you still train hard; it is not a posterior-chain-shaped powder and it is not today’s soccer creatine article. Fifth, stop shopping for a “peak hamstring formula” because Saturday exists.
Read the week like a coach. You want hinging as the main stress, extra curls as leftover you recover from, and no proprietary “posterior matrix.” You do not need a stimulant pre-workout for both hamstring days if sleep is the limiter — save the stronger caffeine for the heavier lower session if you use it at all. You do not need a separate pump product because you added seated curls. You do not need a collagen or BCAA drink to make two hamstring days legal. Collagen is still not a complete muscle protein. If leftover protein after training is also the job, that is a second label, not a reason to skip the second hamstring day. Today’s soccer creatine page still owns the pitch scoop; this page only borrows the same leftover-protein rule for lifters who squat, hinge, and curl.
Before any external checkout, compare protein, creatine, and extras on https://forgedfitness.cloud/supplements so a daily monohydrate, a leftover protein scoop, and a stimulant pre-workout do not all get blamed for the same hamstring measurements. If you want a straightforward 1st Phorm creatine monohydrate path for the hard squatting, hinging, and curling that still runs the week, evaluate Micronized Creatine Monohydrate: add 1 scoop to cold water or juice each day — the labeled serving is 5 grams of creatine monohydrate, including rest days: https://1stphorm.com/products/micronized-creatine-monohydrate/?a_aid=RileyP. If leftover protein after the session is also short, that is a separate complete-protein job such as Phormula-1 mixed as 1 scoop in about 6 ounces of ice-cold water: https://1stphorm.com/products/phormula-1/?a_aid=RileyP. Education first. No hamstring-day stack is required, and no powder outruns two posterior-chain sessions you can repeat.

FAQ
Should you train hamstrings twice a week?
For most healthy adults who lift for size or a stronger hip hinge, yes. Two recoverable hamstring-focused sessions beat one marathon posterior-chain dump. One well-built session still grows muscle. It is usually a worse way to pile quality weekly sets once the last isolation is junk and the hamstrings already worked on squat and deadlift days.
Is one hamstring day a week enough?
It can be, especially if you are new or your weekly set count is still small. Once you need more hard hinges and curls, splitting them across two days usually keeps more sets high quality. Frequency is a volume tool, not a requirement that one day cannot grow muscle.
Do squats and deadlifts already count as hamstring training?
They count as leftover work. Squats and lunges tax the posterior chain if you sit into the hip, but they are still quad-dominant for most people. Conventional deadlifts tax the hip extensors if the back stays quiet. They do not finish the job if you want more direct size work, especially knee flexion. If you already squat and hinge hard twice a week, the second hamstring day should be short, honest curls or a lighter RDL — not a second 20-set smash on a tired low back.
Can you train hamstrings three times a week?
Some intermediates can if each session is shorter, the extra day is not another near-failure RDL smash on top of two heavy lower days, and the hips and low back still recover. It is not automatically better than two good days. If bar speed, sleep, or joint comfort drop, cut volume or drop the third day before you add more isolation.
What should you buy if you add a second hamstring day?
Buy the habit first: two hamstring days you will not skip. Then keep daily creatine monohydrate if you train hard, and leftover complete protein only if food is short. Compare categories on https://forgedfitness.cloud/supplements first. If you want a 1st Phorm path, evaluate Micronized Creatine Monohydrate mixed as 1 scoop — 5 grams — in cold water or juice daily: https://1stphorm.com/products/micronized-creatine-monohydrate/?a_aid=RileyP.
