The dumbbell RDL, short for Romanian deadlift, is a hip hinge. You hold a dumbbell in each hand, push your hips backward with a slight knee bend, lower the weights to about mid-shin, then drive your hips forward to stand tall.
It builds the back of your thighs and your glutes with almost no equipment.
The seated dumbbell shoulder press has you sit against a backrest and press a dumbbell in each hand overhead.
Therefore, the bench holds your torso and your delts spend the whole set pressing. Nothing goes into staying upright.
The swiss ball hamstring curl is a bodyweight exercise where you lie on your back, rest your heels on a stability ball, lift your hips, and pull the ball in with your hamstrings.
No machine, no cable stack, and it still loads both of the hamstrings’ jobs in the same rep.
Rear delt face pulls are a cable exercise where you pull a rope toward your face and finish by pulling it apart, elbows high.
They train the back of your shoulders and the small stabilizing muscles around the joint, but only when you lead with your elbows and finish with your hands rotated back.
The chest supported row has you lie face down on an angled bench and row the weight toward your hips, so the bench holds your torso instead of your lower back holding it.
Nothing fights to keep you in position, so every rep goes into the muscles you want to grow.
In the hack squat vs leg press matchup, the hack squat leans harder on your front thigh muscles (quads) because your torso stays upright and your knees travel forward.
The leg press lets you push more weight with less strain on your lower back.
How to get veiny arms comes down to three things you control and one you do not.
Get body fat low enough that skin stops hiding the vessels, build enough muscle to push those veins toward the surface, and train in a way that raises blood flow.
The three best brachioradialis exercises are the reverse EZ bar curl, the dumbbell hammer curl, and the cable reverse curl.
You can run them with a barbell, dumbbells, a cable stack, or nothing but a resistance band.
Build your shoulder day around the standard dumbbell shoulder press and treat the Arnold press as a lighter accessory if you enjoy it.
The Arnold press does edge it on measured front and side delt activation. You just press meaningfully less weight for that edge, so if you only have room for one pressing movement, keep the standard press.
The average bicep size for men is about 14.1 inches flexed. Relaxed, with the arm hanging at your side, the average drops to roughly 13.5 inches for men in their twenties.
Both numbers are right. They measure two completely different things, which is why one search gives you 13.5, 13.3, 12.7 and 14.6 inches for the same question.
