Stronger Legs at 70: What This Six-Exercise Routine Gets Right
UPLIFT IRON CLUBWhy Strong Legs at 70 Are Not About Finding a Magical Exercise
A fresh Tom's Guide feature built around 70-year-old fitness coach Carrie Sisson makes a useful point before the exercise list even starts: back squats are not compulsory. Her lower-body menu uses Romanian deadlifts, split squats, hip thrusts, leg presses, step-ups and cable kickbacks. The common thread is not age-specific novelty. It is that every movement gives the legs a clear job and can be progressed without forcing one particular lift onto a body that does not like it.
That is a better way to think about strength training after 60 or 70. Aging changes recovery, joint tolerance and the consequences of losing muscle, but it does not create a separate set of muscles that need tiny pink dumbbells and endless easy reps. The National Strength and Conditioning Association's position statement describes resistance training as a powerful intervention against age-related losses of muscle mass, strength and physical function. The training still needs enough challenge to create adaptation.
The practical difference is that exercise selection becomes more valuable. If a back squat irritates your spine or shoulders, a leg press can load the quads heavily without putting a bar on your back. If bilateral work hides a weaker side, split squats and step-ups expose it. If balance is currently the limiting factor, a stable machine can let the target muscles work harder while balance is trained separately.
The goal is not to prove you can train like a 25-year-old. It is to keep producing force, controlling your body and progressing movements you can repeat for years. That is what makes a lower-body program age-friendly: not making it easier by default, but making the hard work sustainable.
Hinges Keep the Posterior Chain in the Conversation
Sisson starts with a Romanian deadlift, and that is a smart counterweight to the squat-dominated way many people think about leg training. A controlled RDL trains the hamstrings and glutes through a hip hinge while asking the trunk to stay rigid. Those muscles matter for far more than the look of the back of the legs; hip extension is part of standing, climbing, carrying and recovering balance.
The movement does not need to be a barbell test. Two dumbbells can make the setup simpler, and the useful range ends when you can no longer keep the spine and pelvis controlled. Think about pushing the hips backward rather than reaching the weights toward the floor. The hamstrings should lengthen under load while the weights stay close to the legs.
For a newer lifter, two or three sets of six to twelve controlled repetitions can be plenty. Leave a couple of clean reps in reserve while technique is becoming automatic. Progress can come from adding a small amount of load, adding a rep within the same range, or improving control at the same load. There is no prize for turning a hinge into a toe-touch competition.
This is also where supervision can be useful. A systematic review comparing supervised and unsupervised exercise in older adults found larger improvements in several strength and balance outcomes with more supervised sessions. That does not mean everyone needs a permanent trainer, but a few coached sessions can shorten the learning curve when a hinge, split squat or machine setup is unfamiliar.
Single-Leg Work Trains Strength You Can Actually Use
Split squats and step-ups earn their place because real life is full of one-leg problems. Stairs, curbs, getting out of a low position and catching yourself after a misstep rarely happen with both feet perfectly symmetrical. Unilateral training lets each side produce force without the stronger leg quietly doing extra work.
A split squat can be scaled almost endlessly. Start with bodyweight and a hand on a rack for balance. Add dumbbells when the pattern is stable. Elevating the rear foot is optional, not a badge of seriousness. The front leg should be doing most of the work, and the range should be deep enough to challenge the hip and knee without losing control.
Step-ups are similarly practical, but box height matters. A lower step that lets you drive through the working leg is more useful than a heroic box that forces you to launch off the floor with the trailing foot. Control the descent as deliberately as the climb. If balance is the weak link, use a rail or rack until strength catches up.
Research on resistance training in older adults consistently points beyond gym numbers. A systematic review found positive effects on gait and balance, including walking speed, while resistance-training studies in people with sarcopenia report improvements in knee-extension strength, gait speed, timed-up-and-go and sit-to-stand performance. That is the connection worth caring about: stronger legs should make movement outside the gym easier, not merely produce a better machine stack.
Machines Are Not Cheating—They Can Let You Train Harder
The leg press is probably the least glamorous exercise on Sisson's list, which is exactly why it deserves attention. A stable machine removes some balance and trunk demands so the quads and glutes can be loaded hard. For an older lifter who is uncomfortable with a bar on the back, that trade can be excellent.
Machines do not make training less functional by default. Function comes from whether the adaptation helps the goal. If stronger knee and hip extensors make stairs, hiking and getting up from a chair easier, the leg press has done something extremely functional even though the movement happened on rails.
Set the seat so you can reach a comfortable depth without the pelvis rolling aggressively away from the pad. Use a load that makes the final repetitions challenging while technique remains repeatable. A simple three sets of eight to twelve can be progressed for months. At home, a goblet squat can fill a similar role if you can hold enough weight comfortably.
This is also a good place to separate strength from power. Strength is the ability to produce force; power adds speed. A meta-analysis of 15 trials and 583 older adults found that power-focused training produced larger improvements in muscle power and several activity-based performance tests than traditional strength training. That does not mean every leg press should be explosive. It suggests that once a base of strength and technique exists, some lighter, faster intent—performed safely—can complement slower heavy work.
Hip Thrusts and Kickbacks Fill Gaps, But They Should Not Run the Program
Hip thrusts and cable kickbacks give the glutes direct work without asking much from the spine. That can be useful, particularly when heavier squat or hinge patterns are limited by comfort elsewhere. A hip thrust is easy to load progressively, while a cable kickback works well as a lower-fatigue finisher.
The mistake would be turning isolation work into the entire lower-body plan. A strong program still needs knee extension, hip extension and preferably some unilateral work. The hip thrust can sit beside an RDL rather than replacing it; the kickback can finish a session after the bigger patterns have already done the heavy lifting.
Use the same progression logic as anywhere else. Pick a rep range, keep the movement controlled and add repetitions or resistance when the top of the range is clean. For hip thrusts, avoid chasing lockout by hyperextending the lower back. Finish with the ribs and pelvis controlled and the glutes doing the work. For kickbacks, a smaller honest range beats swinging the whole torso to move a heavier stack.
This is one reason exercise variety should be purposeful rather than random. Each movement on the six-exercise list has a distinct job. The RDL loads a hinge, split squats and step-ups challenge one leg at a time, the leg press supplies stable heavy knee-and-hip extension, and the hip thrust and kickback add targeted glute volume. You do not need all six every session. You need enough complementary patterns to train the whole lower body without accumulating junk volume.
A Simple Two-Day Lower-Body Plan Beats Collecting Exercises
The most useful way to copy the idea is not to perform all six exercises until your legs stop working. Split the patterns across two weekly sessions. On day one, use a leg press for three sets of six to ten, an RDL for three sets of six to ten, and a supported split squat for two or three sets of eight to twelve per side. Finish with calf work or a light cable kickback if you want it.
On day two, use a goblet squat or another comfortable squat pattern for three sets of eight to twelve, step-ups for three sets of eight to ten per side, and hip thrusts for three sets of eight to twelve. If power is appropriate for your training history, a coach might add a low-risk faster movement early in the session, but speed work should never be improvised when balance or technique is uncertain.
Keep one to three repetitions in reserve on most sets and let progression happen gradually. When every set reaches the top of the rep range with stable technique, add the smallest sensible load. If a joint is irritated, change the range, setup or exercise rather than treating pain as proof that the workout is effective. Beginners, and anyone returning after surgery or injury, should get individualized professional guidance.
Recovery deserves the same respect as loading. Two productive lower-body sessions can beat four mediocre ones if the extra days only repeat soreness and declining performance. Sleep, protein intake and regular walking or other aerobic activity support the work, but they do not replace it. The legs still need resistance that asks them to remain strong.
The bigger lesson from a 70-year-old coach being stronger than ever is not that everyone should copy her exact six exercises. It is that strength remains trainable, and good programming gives you multiple routes to it. You can swap a back squat for a leg press, use support on split squats, choose dumbbells instead of a barbell and still train seriously. Sustainable strength is not watered-down strength. It is hard work arranged so you can keep doing it.
