Deliberately start too light
Your muscles may be ready before your tendons and joints are, so begin at roughly half your old working weights. Leaving 3 or more reps in reserve early prevents the crippling soreness that makes people quit again.
Start at roughly half your old weights, keep reps in reserve, and rebuild over a few weeks; muscle memory returns fast.
After a long layoff, start light, around 50 to 60 percent of what you used to lift, and stop sets well short of failure for the first two to three weeks. Expect to be very sore if you go too hard, so ease in with 2 to 3 full-body sessions a week and add weight quickly as it comes back. Thanks to muscle memory, previously trained lifters regain size and strength far faster than a true beginner.

Two to three full-body sessions a week hit each muscle often and let you relearn the movements. Add weight or reps each session while it comes easily, because the early gains after a break are rapid.
Muscle you built before returns much faster than it did the first time, thanks to retained muscle nuclei. Do not rush the loading anyway, since connective tissue and skill lag behind the muscle for the first few weeks.
