Hamstrings are the ultimate bodybuilding body part. After all, most every other athlete trains them–if they train them–for injury prevention. You rarely notice hams of note on a nonbody-builder, and even most bodybuilders lack the density and dieted-down details to wow a crowd with rear-leg heft or vertical blind lines.
In this article, we help you hammer your hams as we lay bare the top five hamstrings-training blunders. The class is in session.
Mistake #1 Failure to work all areas

In fact, there are three muscles on the back of each thigh, which collectively form the hamstrings, and the biceps femoris has a somewhat different function from the semitendinosus and semimembranosus.
Solutions
- Lying leg curls with your hips on the bench target the biceps femoris (outer hams). Make sure to do at least three sets in each ham workout.
- Seated leg curls target your semitendinosus and semimembranosus (inner hams), so perform at least three sets of seated leg curls in each ham workout.
Pulling your hips off of the bench during lying leg curls will also focus the stress more on this area.
Mistake #2 Insufficient volume

Solutions
- Especially if your legs are lagging, consider training your hamstrings on separate days from your quadriceps. This allows you to focus more on each area.
- If you train quads and hams in the same workout, try combining the two by following an exercise for one with an exercise for the other.
- Do at least 10 sets for hamstrings, and at least three different exercises in each ham workout.
A sample 12-set routine consists of Romanian deadlifts, lying leg curls and seated leg curls, each for 4 sets.
Mistake #3 Lagging intensity

Solutions
- As mentioned previously, give hams their own workout to give them your maximum focus.
- Doing drop sets on lying or seated leg curls is as easy as moving the weight stack’s pin into a higher slot. Make your last set of one-leg curls a drop-set sequence.
- A training partner can easily remove stress from the positive halves of reps and add stress to the negative halves to keep sets going beyond failure.
- If you train alone, you can increase the emphasis on the negative by raising the leg curl weight with both legs, but lowering with just one leg (alternating legs each rep).
- Any ham set can be extended via rest-pause. Pause for 10-20 seconds in the ready position after reaching failure, and then do up to 4 more reps to failure, pause again, and again do up to 4 more reps to failure.
Mistake #4 Minimizing the importance of strength gains

Solutions
- As with any exercise, focus on doing more reps with the same weight or the same reps with more weight from ham workout to ham workout. A workout log can help you monitor your short-term and long-range progress.
- Don’t lock your reps into the 10-15 range. Pyramid at least one exercise per ham workout, increasing the weight and decreasing reps until you reach a maximum 6-rep set.
Mistake #5 Going too fast and too short
Too fast and too short commonly pair up, because when you’re reducing the time of your reps, you’re likely reducing their range of motion, as well. Bodybuilders tend to work the mid-range of leg curls, missing the crucial stretches and contractions.
Solutions
- Slow down leg-curl reps. Take as long as 5 seconds (2 seconds up, 3 seconds down) on each rep.
- Focus on getting a complete stretch and contraction on each rep. Pause briefly at contraction with your ankles as close to your glutes as possible.
- Some machines employ smaller ankle pads or use foot cuffs, which allow you to get a longer range of motion. On the other hand, avoid machines with oversized pads or biomechanical designs that reduce the range of motion.
- To slow down and target each leg individually, do at least one exercise per workout unilaterally.
Chose unilateral standing or kneeling leg curl machines or do your lying or seated leg curls with one leg at a time.
Lessons Learned
- Do exercises for both your outer hams and inner hams in each hamstring workout.
- Do at least 10 sets for hamstrings, and consider breaking up your ham and quad workouts.
- Push sets to failure, and include intensifiers, such as forced reps, drop sets and rest-pause.
- Focus on strength gains, and pyramid some sets.
Slow down your reps on leg curls, and be certain to get full stretches and contractions.
