What legislation required a majority of a state's prewar voters to swear loyalty to the union before restoration could begin?

 The Wade-Davis Bill  (1864)

Detail:

President Abraham Lincoln had proposed lenient approaches to Reconstruction.  Lincoln's plan would have required only 10% of a Southern state's voters to pledge loyalty to the Union, as well as recognizing the freedom of slaves.  

Senator Benjamin F. Wade (from Ohio) and Representative Henry W. Davis (from Maryland) proposed their bill in February, 1864, requiring at least 50% of a state's prewar voters (white males) to swear loyalty to the Union, as well as giving blacks the right to vote.  The measure passed Congress, but Pres. Lincoln did not sign it.  (That's called a "pocket veto.")  So for the time being that measure died.

After Lincoln was assassinated in 1865, the "Radical Republicans" in Congress (who wanted harsher terms imposed on the South) tended to get their way.  President Andrew Johnson vetoed the stern Reconstruction Acts passed by Congress, but Congress overrode his vetoes and implemented their plans.  Tension between Congress and Pres. Johnson also led to the House of Representatives bringing impeachment charges against him.  The Senate narrowly failed to convict Johnson, so he stayed in office.  But Congress was clearly running the show.

take five to 10 minutes to warm up and cool down properly.

plan to start slowly and boost your activity level gradually unless you are already exercising frequently and vigorously.

be aware that training too hard or too often can cause overuse injuries like stress fractures, stiff or sore joints and muscles, and inflamed tendons and ligaments. sports prompting repetitive wear and tear on certain parts of your body — such as swimming (shoulders), jogging (knees, ankles, and feet), tennis (elbows) — are often overuse culprits, too. a mix of different kinds of activities and sufficient rest is safer.

listen to your body. hold off on exercise when you're sick or feeling very fatigued. cut back if you cannot finish an exercise session, feel faint after exercise or fatigued during the day, or suffer persistent aches and pains in joints after exercising.

if you stop exercising for a while, drop back to a lower level of exercise initially. if you're doing strength training, for example, lift lighter weights or do fewer reps or sets.

for most people, simply drinking plenty of water is sufficient. but if you're working out especially hard or doing a marathon or triathlon, choose drinks that replace fluids plus essential electrolytes.

choose clothes and shoes designed for your type of exercise. replace shoes every six months as cushioning wears out.

for strength training, good form is essential. initially use no weight, or very light weights, when learning the exercises. never sacrifice good form by hurrying to finish reps or sets, or struggling to lift heavier weights.

exercising vigorously in hot, humid conditions can lead to serious overheating and dehydration. slow your pace when the temperature rises above 70°f. on days when the thermometer is expected to reach 80°f, exercise during cooler morning or evening hours or at an air-conditioned gym. watch for signs of overheating, such as headache, dizziness, nausea, faintness, cramps, or palpitations.

dress properly for cold-weather workouts to avoid hypothermia. depending on the temperature, wear layers you can peel off as you warm up. don't forget gloves.
